Seller-declared grades, sterling with an approximate US dollar equivalent at £1 ≈ $1.33 (July 2026). What each grade means.
What holds its value across Sweaty Betty
- Named fabric ranges — Power leggings, Super Sculpt and Zero Gravity — which buyers search directly rather than browsing by category
- Discontinued prints and colourways, which develop a following precisely because the brand retires them each season and never reissues
- Pieces with the drawcord waistband and hidden side pocket intact, since the pocket is the feature the range is bought for
- Full matching sets where the bra and the leggings are the same range and colourway, which sell for more than the two pieces listed separately
What pulls Sweaty Betty resale value down
- Pilled inner thighs and a slack waistband, the two places gym leggings fail first and the two a buyer will ask you to photograph
- Sheerness when stretched — hold the fabric over your hand in daylight and say honestly what you see, because every buyer asks
- Fabric softener damage, which coats the elastane and permanently kills the recovery these ranges are bought for
- Missing or illegible care labels, which remove the fabric name and with it the search term the piece would otherwise rank on
Identifying and dating yours
- Photograph the inner waistband label showing the range name and size, because that single label is what the buyer is searching for
- State the inseam length and whether it is the cropped, 7/8 or full-length cut, as the same style ships in three lengths
- Show the fabric stretched over a hand in natural light so opacity is settled before a message is ever sent
What lifts any sports bra, whatever the label
Sports bras are hygiene-sensitive and lose their function through elastic fatigue rather than visible wear.
- Recognised activewear brands
- Elastic with full recovery in band and straps
- Removable pads still present
- Higher support levels, which are in demand
And what pulls one down
- Slack elastic that no longer supports
- Missing removable pads
- Pilling and bobbling on the band
- Unbranded bras, worth very little
Working out what yours is worth
- Stretch the band and check it recovers fully
- Confirm both pads are present
- Wash it and say clearly that you have
What to state in the listing
- Size as labelled, and underband measured flat
- Support level — low, medium or high impact
- Whether pads are removable and included
- Elastic condition, described honestly
Brand, size and support level: “Sweaty Betty Sports Bra, Size M, High Impact”. Support level is a genuine search because it determines what the bra is usable for. Say whether the pads are included, since they are frequently missing.
Preparing and photographing it
- Stretch the band and straps and watch them return. Elastic that stays stretched has done its job and the garment should not be sold as supportive.
- Wash it and check the fabric for pilling, thinning and any lingering odour, which synthetic sportswear holds.
- Note the support level and whether it has removable pads, and check they are present.
- The bra laid flat, front, whole
- The band stretched slightly, showing it recovers
- The straps and any adjusters or clasp
- The label with size, brand and composition, plus any pilling, mark or missing pad
When it sells best, and handing it over
Lifts in January and again in spring. Recognised activewear brands sell within a fortnight; unbranded sports bras are best bundled.
Very cheap to post. Wash before sending and say so in the listing — for intimate activewear that reassurance genuinely converts.
What buyers ask
Which Sweaty Betty leggings are worth the most second hand?
The Power range is the volume seller and the safest resale, but discontinued prints and the sculpting ranges carry a premium because they cannot be bought new any more.
Do gym leggings really sell used?
They do, in large numbers, provided you are honest about pilling and opacity. Photograph the inner thighs and the stretched fabric and the questions mostly stop.
How much is a Sweaty Betty sports bra worth?
Roughly £7 to £28 depending on condition, against £6 to £25 for sports bras generally. The identification points above are what move a listing to the top of that range.
