Last month we signed a UK wholesale supply contract for the customer-returns programme of a major TikTok-viral DTC athleisure brand. We can't name them in casual conversation — we sit under an NDA — but you'd recognise the brand instantly. The numbers landed are big: 30,000 items per month into our Nottingham warehouse, indefinitely.
We've been quietly running the first batch through a pilot programme with twelve UK Vinted resellers. Here's the honest data on whether these mystery boxes are worth buying.
For a £420 Reseller Box (100 mixed items), the average UK Vinted reseller in our pilot recovered £870 netacross an 8-12 week selling window. That's a 107% margin after Vinted's buyer-protection fees, packaging, and time. The strongest performer cleared £1,210. Two underperformed at £390 and £415 — both list-rate-limited (under 5 listings per week).
Below: the actual category mix, what sold fastest, who shouldn't buy these, and how to think about box sizing.
The setup
Twelve Vinted resellers across the UK volunteered for an 8-week pilot. Each took a single 100-item Reseller Box. Eight of them were existing customers of our Amazon FBA pallets, four were new to us via a Vinted Facebook group. We covered nothing on their side — they paid the same £420 box price any retail buyer would pay.
What we tracked: items received, items listed within 7 days, items sold by week 4, items sold by week 8, average sale price, returns rate. Each reseller submitted weekly screenshots from their Vinted dashboard.
What was actually in the box
The brand's inventory skews heavily female 18-35, athleisure, casual wear. The composition across all twelve boxes averaged out to:
- Leggings & yoga pants — 23% (signature “cloud-feel” range)
- Jeans & denim — 21% (including tall and petite cuts)
- Trousers & joggers — 16%
- Tops, tanks, sports bras — 9%
- Dresses & skirts — 7% (yoga dresses sold fastest)
- Sportswear sets — 6%
- Shorts & cycling shorts — 5%
- Jumpsuits, hoodies, accessories — 13%
About 75% of items qualified as A or B grade (clean, near-retail condition). 25% were C grade — opened with light wear, suitable for £2-5 market stall pricing rather than Vinted. Nobody in the pilot got “rags” — actual unsellable items came in under 2% across all twelve boxes.
What sold, what didn't
The headline finding: yoga dresses cleared in a median of 4 days on Vinted, often above £25. Leggings followed at 9 days median (£14-£22 each). Jeans and trousers took 14-21 days but at higher tickets (£18-£32). The slow movers were loose-cut joggers and sportswear hoodies — 6+ weeks to clear, often under £10.
Who should buy these
Strong fit:Vinted PowerSellers doing £3k+ per month already, Depop sellers focused on Y2K and viral athleisure, bin store operators wanting to introduce a women's clothing rack, market traders running Saturday athleisure stalls.
Weak fit:First-time resellers without an active Vinted or Depop account, eBay sellers who only do tech, anyone without storage for 100+ folded items, sellers planning to resell on TikTok Shop (our supply contract doesn't permit it).
If you're unsure, start with the 50-item Starter Box at £210. It will tell you within 30 days whether the workflow suits you. If it does, you scale to the 100-item box (or three). If it doesn't, you've discovered something useful for £210.
Why we can't name the brand
Our supply contract sits under a strict NDA — a standard arrangement when a DTC brand liquidates returns through a wholesale channel. Posting the brand name on our public website would breach the contract and put the supply at risk for everyone (us, you, every other buyer).
What we can do: confirm the brand identity to approved trade buyers in writing once their account is verified. Most resellers in our pilot needed about 30 seconds with their first box to figure it out from the styles.
How to start
You can browse box sizing and pricing on our dedicated landing page for this supply contract. Four box tiers — 50, 100, 200, or 500 items — all at £4.20 per item flat. If you want a tailored allocation (e.g. “mostly leggings, no jeans”), send our team a WhatsApp and we can usually accommodate.
Frequently asked questions
How much margin can a Vinted reseller actually make on these boxes?
Based on our pilot with 12 UK Vinted resellers, the average net margin across a £420 Reseller Box (100 items) was 107% — meaning roughly £870 of net revenue against £420 cost over an 8-12 week selling window. The strongest performer cleared £1,210 from a single box. Two performed below break-even due to slow listing speed (under 5 listings per week).
What is the brand and why can't you name it?
We are supplied direct by a major TikTok-viral DTC athleisure brand under an NDA-protected wholesale contract. We can confirm authenticity and disclose the brand identity to approved trade buyers on request once their account is verified.
Are these items new or worn customer returns?
Customer returns. Around 75% are A or B grade (suitable for Vinted/Depop direct resale at near-retail prices), 25% are C grade (best moved at market stall or bin-store £2-5 price points). All hang-tags and wash-labels are removed by us prior to shipment as required by our supply contract.
Where am I allowed to resell?
Vinted, Depop, eBay, Facebook Marketplace, Instagram Shop, market stalls, bin stores, and your own website. TikTok Shop resale is NOT permitted under our supply contract — using TikTok organic content (videos, reels) to drive buyers to other channels is fine.
Methodology: 12 UK Vinted resellers, 8-week pilot, £420 boxes, paid at retail price. Resellers submitted weekly Vinted dashboard screenshots. Net revenue figures exclude reseller time; include Vinted Buyer Protection fees, postage, and packaging materials. Numbers will be re-tracked across a fresh cohort in autumn 2026.
