Used activewear sets in the UK typically sell for £15 to £55 (about $20 to $74). Matched activewear sets sell for more than the pieces apart, so confirm both items are the same line and colourway before you list.

Selling an activewear set in the UK
Most private sales settle by bank transfer or cash on collection. Faster Payments clear in seconds, which makes a transfer as safe as cash for the seller — wait for it to land before the item leaves your hands.
The UK has the deepest second-hand habit of any of our markets — charity shops, car boot sales and online resale have been mainstream here for decades, so buyers arrive already comfortable with used goods and already know roughly what things are worth.
Distance selling rules bind traders, not private sellers, but an item must still be as described and anything sold as working must actually work.
Second-hand demand peaks in January, in the weeks before Christmas, and at the start of the academic year in September.
Working out what yours is worth
- Stretch the fabric against the light to check opacity
- Inspect the inner thigh area for pilling
Getting it ready
- Check the top and bottoms are genuinely matching, same brand line and same colour batch.
- Note both sizes separately and the brand’s style names if they have them.
Photograph
- Both pieces laid out together
- Both size and composition labels
- Seams, waistband and any pill, mark or pull
Put in the description
- Brand and specific product line
- Sizes of both pieces, stated separately
- Fabric composition, and whether opaque when stretched
Brand, line and both sizes: “Gymshark Vital Seamless Set, Top S Leggings S, Sage”. Brand line names are searched exactly in activewear. State both sizes and confirm it is a genuine matching set.
Light and cheap to post. Wash both pieces before sending and say so — on used activewear that single sentence resolves the buyer’s main hesitation, and it costs you nothing but a wash cycle.
It costs nothing to list
There is no listing fee, no selling fee and no commission, so the £55 a buyer pays is the £55 you keep. You and the buyer settle up and arrange the handover between yourselves; WishThrift does not hold the money or ship the item.

Common questions
Where can I sell an activewear set in the UK?
List it free on WishThrift and deal with the buyer direct. There is no selling fee, so the whole amount stays with you. Most private sales settle by bank transfer or cash on collection. Faster Payments clear in seconds, which makes a transfer as safe as cash for the seller — wait for it to land before the item leaves your hands.
What sizes are the pieces?
Give both. Buyers frequently need different sizes top and bottom.
Does used activewear sell?
Recognised brands sell well; unbranded sets sell for very little. Fabric condition matters more than in most clothing.
Should sets be sold together?
Yes. Matching sets sell noticeably better than separates in this category.
