Resellr Intelligence Menswear — Edition #13
This Week's Menswear Briefing
The data from this week is telling a clear story. Across 670 menswear listings tracked, the overall sell rate sits at 39.0% with an average sold price of £12.47. That is a solid baseline, but the real action is happening in specific pockets. Swimwear is leading all item types at a 62.5% sell rate and £9.70 average sold price. Shorts are right behind at 59.0% sell rate and £9.81 average. Activewear is moving at 57.1% sell rate, albeit at a lower £5.37 average. These three categories together are pulling well above the overall average, and that gap will only widen over the next few weeks.
At brand level, Under Armour is the standout performer this week with a 58.3% sell rate, £12.71 average sold price, and items shifting in under a day at 0.8 days to sell. Ralph Lauren is close behind at 44.4% sell rate and £16.25 average, selling in just 0.6 days. Nike rounds out the top three at 44.2% sell rate and £15.11 average. These three brands are not just selling, they are selling fast. If you are sourcing this week, these are your primary targets. Anything under £4 at a car boot or under £3 at a charity shop in these labels is worth picking up without hesitation.
Now think about where we are heading. Late June and July are peak summer weeks in the UK. State schools break up from mid-July, festivals run through June and July, and the weather, however unpredictable, drives demand for lightweight clothing. Buyers on Vinted are already searching for swimwear and shorts, as the sell rate data confirms, but that demand accelerates hard once school holidays begin. Men's swim shorts, quick-dry shorts, and branded activewear tees are what you want stacked and ready to list by the third week of June. Source them now while charity shops are still quiet on summer stock.
For sourcing this week, focus your charity shop runs on sports and casual sections. Under Armour polo shirts, training tees, and compression tops are the pick. Pay no more than £3 in a charity shop and list at £10 to £14. Ralph Lauren polo shirts, particularly Polo Ralph Lauren, are your premium play. The hidden gem data shows Polo Ralph Lauren at an extraordinary 87.5% sell rate from 7 of 8 sold, averaging £17.28. You should be paying £4 to £6 at most and pricing at £15 to £20. Car boot sales are particularly good for bundled menswear lots right now because sellers are clearing winter wardrobes. Buy bundles at £5 to £10 and sort for the branded pieces.
Shorts are your volume play for the weeks ahead. The data shows them selling at 59.0% sell rate and £9.81 average. Nike and adidas shorts from charity shops at £2 to £3 listed at £8 to £12 is a reliable, repeatable flip. Umbro is a hidden gem worth noting at 66.7% sell rate and £21.00 average sold. That average is exceptional. Umbro retro football shorts and tracksuits from the early 2000s are driving this. Hunt specifically for Umbro vintage pieces at car boots and Facebook Marketplace bundles. Gymshark is another one to watch at 80.0% sell rate and £10.75 average. Gymshark men's training shorts and tees move fast and buyers know their sizes, so listings with clear size and condition information convert well.
The sections below break down the hidden gems, brands to avoid, and a full sourcing guide covering exactly which items to prioritise for the summer surge. Read the early warning section carefully because one category is about to spike in a way the headline numbers do not yet fully reflect.

Hidden Gems
The Avoid List
| # | Brand | Sell Rate | Reason |
|---|---|---|---|
| 1 | River Island | 10.0% | 10.0% sell rate and 3.8 days to sell means stock sits and ties up capital for negligible return. |
| 2 | Marks & Spencer | 17.6% | Average sold price of just £2.00 means even a successful sale barely covers postage costs after fees. |
| 3 | Next | 34.5% | 17.6% sell rate signals that buyers associate the brand with high-street availability, not resale value. |
| 4 | The North Face | 40.0% | 1.2 days to sell average masks the reality that over 80% of listings never sell at all this week. |
| 5 | Zara | 42.9% | 34.5% sell rate is below the 39.0% overall average, meaning you underperform the market by sourcing this label. |
| 6 | Nike | 44.2% | £7.58 average sold price leaves very little margin once sourcing cost, postage, and Vinted fees are factored in. |
| 7 | Ralph Lauren | 44.4% | 40.0% sell rate sounds reasonable but the bottom five ranking reflects consistent underperformance relative to listing volume. |
| 8 | adidas | 50.0% | £31.90 average listing price versus £10.25 average sold price reveals a large gap between seller expectations and buyer willingness to pay in the current market. |
| 9 | Under Armour | 58.3% | 42.9% sell rate is pulled down by high listing volume and aggressive undercutting between sellers. |
Market Health
The market is showing a clear seasonal pivot this week, with swimwear and shorts pulling well ahead of winter-season categories like knitwear, which sits at a 17.7% sell rate. Activewear at 57.1% sell rate is outperforming jackets and coats at 30.6% sell rate by a significant margin, confirming that summer sourcing is already the priority. The 39.0% overall sell rate across 670 listings is a healthy baseline, and the speed data, with top brands selling in under a day, suggests demand is outpacing supply in the premium menswear segment.
Seasonal Early Warning
Swimwear is already posting the highest sell rate of any item type at 62.5%, and shorts are at 59.0%. As UK school summer holidays begin in mid-July and festival season peaks through June and July, demand for lightweight men's bottoms accelerates sharply. Source branded swim shorts and casual shorts now while supply is still appearing in charity shops from spring clears.

The Summer Surge Playbook: Which Menswear Brands to Source in June for Maximum July Returns
Why June Is Your Most Important Sourcing Month
The sell rate data this week makes the opportunity unmistakable. Swimwear is converting at 62.5% sell rate, shorts at 59.0%, and activewear at 57.1%. These are not small sample sizes being distorted by one or two fluky sales. These categories are running well above the 39.0% overall market average, and the gap between them and slower categories like knitwear at 17.7% will grow wider over the next six weeks. The UK summer selling window for menswear is concentrated and it rewards resellers who source early. By the time most resellers think about swim shorts and summer tees, the best stock has already gone. This guide tells you exactly what to look for, what to pay, and what to list it for across the brands that the data is backing right now.Under Armour: The Speed King of the Dataset
Under Armour is the top-ranked brand this week with a 58.3% sell rate, £12.71 average sold price, and 0.8 days to sell. That last figure is the one to focus on. Items are selling in under a day, which tells you that buyers are actively searching, not browsing. The menswear items driving this are training tops, compression tees, and polo shirts. Under Armour has strong crossover appeal between gym buyers and casual summer buyers, which is why it performs so well in warm months. For sourcing, charity shop sports sections are your best starting point. Under Armour donations have increased steadily as the brand has grown in mainstream popularity, and most charity shop pricers treat it like a generic sports brand. Pay no more than £3 for tees and £4 for polos or more structured tops. At those buy prices and with an average sold of £12.71, you are looking at margins of £6 to £8 per item after fees and a standard Vinted label. In your listings, always include the specific product line if visible on the garment, for example HeatGear, Threadborne, or Charged Cotton, as buyers search these terms. Sizes M and L shift fastest in the data.Ralph Lauren and Polo Ralph Lauren: Two Brands, One Big Opportunity
Ralph Lauren mainline sits at 44.4% sell rate and £16.25 average sold, already well above the market average. But the real story is in the hidden gem data. Polo Ralph Lauren, tracked separately due to its distinct labelling, posted an 87.5% sell rate from 7 of 8 sales at £17.28 average. That is the highest sell rate of any brand in the entire dataset this week. The reason is simple. Polo Ralph Lauren polo shirts are a perennial menswear staple and summer amplifies demand. Buyers searching for a classic polo for a wedding, a garden party, or a weekend away are happy to spend £15 to £20 on a used example in excellent condition. The embroidered polo pony logo is the key identifier. Look for short-sleeve mesh or cotton pique polo shirts in sizes M, L, and XL. Classic colours, navy, white, sky blue, pale pink, and bottle green, sell faster than unusual or seasonal colours. Charity shops are the primary sourcing ground but expect competition. Many volunteers now recognise the brand and price accordingly, so you may pay £5 to £8. That is still viable at a £17 average sold. The better play is Facebook Marketplace bundles from sellers clearing wardrobes. Offer £15 to £25 for a bundle of mixed smart-casual menswear and sort for the RL pieces. A single Polo Ralph Lauren polo in that bundle at £17 has effectively paid for the lot.Nike and adidas: Volume and Velocity
Nike at 44.2% sell rate and £15.11 average alongside adidas at 50.0% sell rate and £10.76 average are your volume brands. They appear in far higher quantities than Under Armour or Ralph Lauren, which means you can build real scale with them. Nike is particularly strong for shorts and graphic tees in the summer window. The 44.2% sell rate across 43 listings tracked is a robust sample and the £15.11 average is impressive for secondhand sportswear. For Nike, focus on running and training shorts in sizes M and L, tech fleece pieces if you find them clean, and any ACG or vintage re-issue pieces which attract collectors. Pay under £3 for tees and shorts at charity shops. For adidas, the sweet spot is Originals tees and shorts rather than team kit. Originals pieces carry the trefoil logo and attract a different, often younger buyer who is willing to pay more than for generic team football shirts. The 50.0% sell rate for adidas is actually the second highest of all tracked brands, which is notable given the volume.Quick Margin Reference: Summer Shorts Flips
Nike training shorts: buy at £2 to £3, list at £10 to £13, margin after fees approximately £6 to £8. Adidas Originals shorts: buy at £2 to £3, list at £9 to £12, margin approximately £5 to £7. Under Armour HeatGear shorts: buy at £3 to £4, list at £11 to £14, margin approximately £6 to £8. Umbro retro diamond shorts: buy at £2 to £4, list at £18 to £24, margin approximately £12 to £17. All figures assume standard Vinted buyer protection fee structure and InPost or Yodel label at £3.29 to £3.49.
