Complete listing requirements, feed specifications, and optimization tips for ASOS Marketplace.
ASOS Marketplace is a curated online platform operated by ASOS plc, one of the UK's largest fashion e-commerce retailers. Launched in 2010 as a dedicated space for independent boutiques and vintage sellers, ASOS Marketplace gives fashion-forward brands access to ASOS's audience of over 25 million active customers worldwide. The platform is designed specifically for fashion, accessories, and beauty products, making it a highly targeted channel for sellers in these categories. Unlike ASOS's main retail operation, which buys and resells inventory, ASOS Marketplace operates as a true marketplace where independent sellers manage their own inventory, pricing, and fulfillment.
Listing products on ASOS Marketplace requires sellers to meet strict brand and quality standards. ASOS curates its marketplace carefully, and all new seller applications go through an approval process to ensure they align with the ASOS brand aesthetic and customer expectations. Product listings must include high-quality images shot on models or styled flat-lays (ghost mannequins are also accepted), detailed product descriptions with accurate sizing information, and proper categorization within ASOS's fashion taxonomy. The platform supports both new and vintage/pre-loved items, but all products must meet ASOS's quality and presentation standards to remain listed.
ASOS Marketplace provides sellers with a dedicated seller dashboard (Seller Studio) for managing listings, orders, and performance analytics. Product data can be uploaded individually through the dashboard or in bulk via CSV file imports. The platform supports integration with popular e-commerce tools and inventory management systems. ASOS Marketplace charges a commission on each sale rather than monthly fees, making it accessible for smaller sellers and emerging brands. For product data management, integrating a PIM system with ASOS Marketplace ensures consistent, high-quality product information that meets the platform's stringent visual and data requirements, reducing listing rejections and improving conversion rates.
Required and optional fields for product listings on this marketplace
Product titles should be descriptive and fashion-forward, clearly communicating the brand, product type, and distinguishing features such as color, pattern, or fit. Avoid generic titles and include style-relevant keywords that ASOS customers are likely to search for. Titles should not contain promotional language, excessive capitalization, or special characters. Use a conversational yet professional tone that matches ASOS's brand voice.
Vintage Levi's 501 High-Waisted Straight Leg Jeans in Washed BlueThe product description should paint a picture of the item and help customers understand the fit, fabric, and styling possibilities. Include practical details such as measurements, fabric composition, care instructions, and condition (for vintage items). Descriptions should be engaging and align with ASOS's fashion-forward editorial style. Avoid using generic or copy-pasted descriptions, as ASOS may reject listings that don't meet their content quality standards.

Button fly closure. Five-pocket styling. Pair with a cropped tee and chunky trainers for effortless weekend style.ASOS Marketplace requires high-quality fashion photography. The main image must show the full product, ideally on a model or as a styled flat-lay on a clean background. Ghost mannequin photography is also accepted. Images must be well-lit with accurate color representation. No watermarks, logos, collages, or promotional text overlays are allowed. Additional images should show different angles, fabric details, closures, and how the item can be styled. Image quality is one of the primary reasons listings get rejected on ASOS Marketplace.
Main image: product on model against a plain background. Additional: close-up of fabric, detail shots, back view, styling alternativesProduct prices must be set in the seller's base currency, with GBP as the primary currency for UK sellers. ASOS Marketplace automatically handles currency conversion for international customers. Prices should be competitive within the fashion marketplace context and reflect the quality and brand positioning of the product. ASOS reserves the right to flag or remove listings with prices deemed inconsistent with marketplace standards.
45.00The brand name must accurately identify the product's brand. For vintage sellers offering products from established brands, the brand name must match the original manufacturer. Sellers with their own label should use their registered boutique/brand name. Counterfeit or misrepresented brand names will result in immediate listing removal and potential account suspension. ASOS Marketplace takes intellectual property compliance very seriously.
Levi'sProducts must be assigned to the most specific category within ASOS's fashion taxonomy. Correct categorization ensures products appear in relevant browse pages, search results, and filtered views. ASOS uses a fashion-specific category structure organized by gender, product type, sub-type, and occasion. Miscategorized products may be moved or delisted by ASOS's curation team.
Women > Jeans > Straight Leg JeansAll clothing items must include accurate sizing information using ASOS's standardized size guide values. Sizes should be mapped to the appropriate regional size system (UK, EU, US). For vintage items where original sizing may differ from modern standards, sellers should include actual measurements (bust, waist, hip, length) in centimeters and inches. Inaccurate sizing is a leading cause of returns on fashion marketplaces and will negatively impact seller ratings.
UK 10 / EU 38 / US 6Products must be tagged with a color from ASOS's predefined color palette. This enables customers to filter products by color in search results. If a product features multiple colors or a pattern, select the dominant color. Ensure the color tag accurately reflects what the customer will receive, as color discrepancies are a common complaint in online fashion retail.
BlueASOS Marketplace supports new products from independent brands and boutiques, as well as vintage and pre-loved items. For vintage and pre-loved items, the condition must be clearly stated, including any flaws, repairs, or signs of wear. ASOS defines 'vintage' as items from a previous era (typically 20+ years old) and 'pre-loved' as second-hand items in good condition. All items must meet ASOS's minimum quality standards regardless of category.
Vintage - Excellent condition, minimal signs of wearFabric composition must be accurately listed for all clothing and textile products. This is a legal requirement in many markets including the UK and EU. List all materials by percentage in descending order (e.g., 80% Cotton, 20% Polyester). For vintage items where original labels may be missing, provide your best assessment and note that exact composition may vary. Include details about fabric weight, texture, or special treatments where relevant.
100% Cotton Denim, 14oz heavyweightWhile not always mandatory, providing detailed measurements is strongly recommended, especially for vintage items where sizing may not correspond to modern standards. Include all relevant measurements for the product type (e.g., bust, waist, hips, and length for dresses). Accurate measurements significantly reduce return rates and improve customer satisfaction. ASOS provides measurement guidelines for each product category.
Waist: 28in (71cm), Hip: 38in (96.5cm), Inside Leg: 32in (81cm)Care instructions help customers maintain their purchases and are a legal requirement for new clothing in many jurisdictions. Include washing, drying, ironing, and dry cleaning instructions. For vintage items where care labels may be missing, provide general care recommendations based on the fabric composition. Proper care information reduces returns and increases customer confidence in purchasing.
Machine wash cold, tumble dry low, do not bleach, iron on medium heatCSV flat file, manual entry via Seller Studio
ASOS Marketplace supports product data submission through its Seller Studio dashboard and via CSV bulk upload files. The CSV template can be downloaded from the Seller Studio and includes fields for all required and optional product attributes. Individual listings can be created and edited directly through the dashboard interface. ASOS Marketplace also supports integration with select e-commerce platforms and inventory management tools through third-party connectors. The platform does not currently offer a public API for product data management, so most automated integrations rely on CSV file exchange or third-party middleware solutions.
ASOS Marketplace uses a fashion-specific category taxonomy organized primarily by gender (Women, Men), then by product type (Clothing, Shoes, Accessories, Face + Body), and then into increasingly specific sub-categories (e.g., Women > Clothing > Dresses > Midi Dresses > Floral Midi Dresses). The taxonomy is optimized for how fashion customers browse and filter products, with categories aligned to current fashion trends and shopping behaviors. ASOS periodically updates its category structure to reflect seasonal trends and emerging fashion categories, so sellers should regularly verify their category mappings are current.
Detailed requirements for product titles, descriptions, images, and pricing
Avoid these common issues that cause product listings to be rejected or suppressed
Poor image quality or non-compliant photography style
Re-photograph products using professional lighting and a clean background. Ensure images are at least 870 x 1262 pixels in portrait orientation. Use on-model photography, styled flat-lays, or ghost mannequin shots. Remove all watermarks, logos, and text overlays. ASOS Marketplace prioritizes visual quality, so investing in good photography is essential for acceptance.
Product does not align with ASOS Marketplace's brand and audience
ASOS Marketplace curates its sellers to maintain a cohesive fashion-forward brand experience. Ensure your products target the 16-35 age demographic and align with current fashion trends. Review the ASOS Marketplace seller guidelines and study existing successful boutiques on the platform for style direction. Products that are overly niche, outdated in style, or not fashion-related will be declined.
Incomplete or inaccurate product information (missing sizes, fabric, or measurements)
Ensure every listing has complete size information using ASOS's standard size values, accurate fabric composition percentages, and care instructions. For vintage items, include actual garment measurements in both centimeters and inches. Double-check that all required fields are filled in and that the information matches the product being sold.
Inaccurate or misleading brand attribution
Verify that the brand name matches the product's actual manufacturer or label. Do not use ASOS's own brand names for non-ASOS products. For own-label products, use your registered boutique brand name. Counterfeits, replicas, or brand-inspired items are strictly prohibited and will result in immediate removal and potential legal action.
Vintage items listed without proper condition description or with undisclosed flaws
Provide a thorough and honest condition assessment for all vintage and pre-loved items. Disclose any flaws, stains, repairs, missing buttons, or signs of wear in the description and show them clearly in photographs. Use ASOS's condition ratings accurately. Transparency builds trust and reduces returns, while hidden flaws lead to complaints, returns, and seller rating drops.
Pricing significantly above or below market value without justification
Research comparable items on ASOS Marketplace and other fashion platforms to ensure your pricing is competitive and realistic. Extremely low prices can suggest counterfeit goods, while prices far above market value for common items will deter customers and may be flagged by ASOS. For rare vintage pieces, include details in the description that justify premium pricing (designer, era, condition, rarity).
Listing contains prohibited items (counterfeit goods, restricted materials, non-fashion items)
Review ASOS Marketplace's prohibited items policy before listing. The platform does not allow counterfeit goods, items made from endangered animal materials (real fur, exotic skins without CITES documentation), weapons, or non-fashion products. Ensure all products comply with UK and EU product safety regulations. If in doubt about a specific item, contact ASOS Marketplace seller support before listing.
Duplicate listings or excessive similar listings flooding the feed
Avoid creating multiple identical or near-identical listings for the same product. If you have the same item in multiple sizes, use size variants within a single listing rather than creating separate listings. ASOS Marketplace may remove duplicate listings to maintain a clean browsing experience. Consolidate your catalog and ensure each listing represents a distinct product.
Best practices to improve your product listing performance and visibility
ASOS Marketplace is a visual-first platform where image quality directly impacts sales performance. Invest in on-model photography with clean backgrounds and consistent lighting. Show garments from multiple angles and include close-up detail shots. Products photographed on models consistently outperform flat-lays in conversion rates. If you cannot afford models, high-quality ghost mannequin photography is an effective alternative. Maintain a consistent photographic style across your boutique to build brand recognition.
ASOS customers expect fashion-forward, engaging product copy. Write descriptions that combine practical information (fabric, fit, measurements) with styling suggestions and lifestyle context. Study ASOS's own product descriptions for tone and structure. Start with a compelling opening that describes how the item looks and feels, then layer in technical details. Include styling tips that help customers imagine wearing the piece in their daily life. Descriptions that tell a story sell more than those that simply list features.
Align your product listings and new inventory drops with fashion seasons and ASOS's promotional calendar. List summer collections in early spring, festival wear before festival season, and partywear ahead of the holiday period. ASOS Marketplace features curated edits and seasonal campaigns that can drive significant traffic to aligned sellers. Stay current with fashion trend reports and adjust your inventory and keywords accordingly.
ASOS Marketplace boutiques with strong social media presence consistently outperform those without. Use Instagram, TikTok, and Pinterest to showcase your products with styling inspiration and behind-the-scenes content. Link directly to your ASOS Marketplace boutique page from your social profiles. Engage with the ASOS community using relevant hashtags. Many successful ASOS Marketplace sellers attribute a significant portion of their sales to social media-driven traffic.
ASOS Marketplace customers browse boutiques as well as individual products. Create a strong, consistent brand identity across your entire storefront. Use a professional boutique banner and profile image. Maintain a consistent photographic style, price range, and aesthetic across all listings. A curated, cohesive boutique encourages customers to browse multiple items and increases average order value. Update your boutique regularly with new stock to signal an active, engaged seller.
Size and fit uncertainty is the number one barrier to purchase on fashion marketplaces. Reduce this friction by providing comprehensive sizing information including garment measurements, fit descriptions (true to size, oversized, slim), and model sizing references. For vintage items, always include actual measurements as historical sizing varies significantly. Consider adding a size guide to your boutique profile. Listings with detailed sizing consistently see lower return rates and higher conversion.
ASOS Marketplace monitors seller performance including response times, dispatch times, and customer satisfaction scores. Aim to respond to all customer inquiries within 12 hours. Dispatch orders within the committed timeframe and provide tracking information. Handle returns and refunds promptly and professionally. High seller ratings improve your boutique's visibility within the marketplace and increase customer confidence. ASOS may feature top-rated boutiques in curated edits and promotional placements.
Step-by-step guide to getting your products live on this marketplace
Visit marketplace.asos.com and submit your seller application. Prepare a strong brand pitch including your boutique concept, target audience, sample product images, and brand story. ASOS reviews applications for brand alignment, product quality, and photography standards. Once approved (typically 2-4 weeks), set up your boutique profile with a professional banner image, brand bio, shipping policies, and returns information. Configure your payment details for receiving commission-deducted payouts.
Before listing, prepare all product data including accurate titles, detailed descriptions, fabric compositions, sizing information, and care instructions. Invest in high-quality product photography that meets ASOS's standards: minimum 870 x 1262 pixels, clean backgrounds, and on-model or ghost mannequin styling. For vintage items, document accurate measurements and any condition details. Organize your data in a spreadsheet matching ASOS Marketplace's CSV template format for efficient bulk uploading.
Log into Seller Studio and create your listings either individually through the dashboard interface or in bulk via CSV upload. For each listing, select the most specific category, add all required fields (title, description, price, brand, size, color, fabric, condition), and upload your product images with the main image first. Set your pricing to be competitive while accounting for the 20% commission. If using a PIM system, export your data in the ASOS Marketplace CSV format for efficient upload and ensure all required fields are mapped correctly.
