How to Build a Marketplace Website for Vintage Streetwear

1. 1

   Step 1 · Curation

   Set your authenticity and condition bar

   Decide what qualifies before anyone lists. Write down which brands and eras you accept, what counts as deadstock, and a simple condition scale such as deadstock, excellent, good and worn. Ask sellers for photos of tags, labels and stitching on every item. A clear bar keeps fakes out and makes your listings comparable at a glance.

   Tradly: Tradly lets you approve sellers and listings before they go live, so only items that meet your bar reach buyers.

   Step 2 · Catalogue

   Shape the catalogue around how collectors search

   Collectors search by brand, era, size and fit, not by generic categories. Set up attributes for brand, decade, tagged size, pit-to-pit and length measurements, and condition grade. Measurements matter more than the size on the tag, because vintage sizing varies a lot between brands and decades.

   Tradly: Tradly's custom listing attributes and filters let buyers narrow a search to the brand, decade and measurements they want.

   Step 3 · Sellers

   Recruit and verify your first sellers

   Start with 15–30 sellers whose taste and honesty you already know from the scene. Invite them personally, check their past sales, and ask each one to list a small batch of their best pieces first. A strong first catalogue from known sellers does more for trust than any amount of marketing.

   Tradly: Tradly includes seller sign-up, verification and an approval flow, and every seller gets a dashboard to manage listings and payouts.

   Step 4 · Escrow

   Protect every sale with escrow

   When a jacket costs a few hundred dollars, buyers won't pay a stranger directly. Hold the payment until the buyer confirms the item arrived as described, then release it to the seller minus your commission. Write a short policy for what happens if an item doesn't match its listing, and link it from every product page.

   Tradly: Tradly's escrow checkout holds payment and releases it on delivery confirmation, with automatic seller payouts and your commission split.

   Step 5 · Shipping

   Ship tracked and set clear packing rules

   Require tracked shipping on every order and ask sellers to photograph the item packed before it leaves. Offer local pickup for buyers who want to see a piece in person. Visible tracking reduces 'where is my order' messages and gives you a clear record if a parcel goes missing.

   Tradly: Tradly supports shipping methods, couriers and local pickup, with live order tracking for buyers and sellers.

   Step 6 · AI

   Use AI for buyer questions and listing review

   Buyers message about fit, flaws and shipping at all hours, and new sellers ask what passes your authenticity bar. An AI agent trained on your condition scale, sizing guide and policies can answer most of these instantly. Behind the scenes, connect the marketplace to an AI assistant so you can ask which listings are waiting for approval or which orders haven't shipped, and act on them in one conversation.

   Tradly: Tradly Agent Builder trains an agent on your condition scale and policies, and Tradly MCP (mcp.tradly.app) lets Claude or ChatGPT review pending listings, orders and shipments for you.

   Step 7 · Drops

   Launch with a drop, then keep the community active

   Streetwear buyers respond to timing. Open with a scheduled drop of your best curated pieces and announce it to your community a week ahead. After launch, let buyers follow their favourite sellers, encourage reviews after every sale, and run regular themed drops by era or brand so people have a reason to come back.

   Tradly: Tradly includes limited-time drops, coupons and referral rewards, plus follows, chat and reviews, on the web and native mobile apps.

Plus 50+ integrations, full REST API & JS SDK, and the Marketplace Kit for ready-made multi-vendor flows.
