Sell Your Used Swimwear — 0% Fees

Used swimwear typically sells for £8 to £35, and on WishThrift it costs you nothing to list — no fee, no commission, so you keep the whole amount you agree. Used swimwear sells, but only with hygiene addressed head-on — confirm the hygiene liner is intact and say plainly how it has been cared for.

The short version

Typical range: £8 – £35 — see the full swimwear value guide
What decides your price: condition, and how well you evidence it in photographs
Cost to sell here: nothing, at any price

Before you photograph it

Ten minutes here is worth more than anything else you will do. Buyers are deciding between your listing and someone else’s, and preparation is what visibly separates the two.

Check the hygiene liner is present and intact on bikini bottoms and one-pieces.
Check the elastic at the leg and back, and the fabric for chlorine damage, thinning or bobbling.
Wash it properly and say so, and confirm all ties, clasps and padding are present.

The photographs that sell swimwear

Four photographs do almost all the work. Shoot in daylight, near a window, with the item against something plain — and do not use the flash, which flattens texture and hides exactly what buyers are trying to see.

Laid flat, front, whole garment
The hygiene liner, showing it is intact
The elastic at legs and back
The size tag, plus any thinning, bobbling or mark

Photograph the flaws too. It feels counterproductive, but a listing that shows the worst of an item gets fewer questions, fewer withdrawn offers and fewer arguments at handover. Buyers who can see the damage stop imagining something worse.

Writing the title and description

Style, brand and size: “High Waisted Bikini Set, Size 12, Hygiene Liner Intact”. Saying the liner is intact is unusual and directly addresses the buyer’s hesitation. State whether padding is removable and included.

Then state these in the description, because a buyer who has to ask is a buyer who might not bother:

Style, brand and size, with the cup size for bikini tops
Whether the hygiene liner is present and intact
Whether padding is included and removable
Elastic condition and any chlorine damage or thinning

What buyers will actually ask

You will receive the same three messages about swimwear. Answering them in the listing itself removes the back-and-forth, and answering them well when they do arrive is what turns an enquiry into a sale.

“Is the hygiene liner still there?”

Check and confirm explicitly. It is the question behind every used swimwear purchase and answering it up front is what makes the sale.

“Has it been worn in chlorine?”

Say honestly. Chlorine thins and fades swim fabric, and buyers can usually tell once it arrives.

“Is the padding included?”

Check the cups. Removable pads go missing in the wash and their absence should be stated.

Pricing it so it actually sells

Start from the honest condition grade rather than the price you hope for. WishThrift listings use five grades — New with Tags, Like New, Good, Fair and For Parts — and what each grade means is worth reading before you choose, because grading up is the most expensive mistake sellers make. It does not raise the price; it produces a buyer who arrives expecting something else.

The swimwear value guide prices all five grades for this item. Pick your grade, take the figure, and if you sit between two grades price toward the lower one. Items priced honestly sell faster than items priced hopefully, and on a free platform there is no fee eating the difference anyway.

What you keep, compared

On a £21 sale — roughly the middle of the range for swimwear — here is what the commission-charging platforms would take, and what you would keep on each:

Where you sell it	Fee	You keep
WishThrift	£0	£21
Poshmark	−£4	£17
eBay	−£3	£18
Mercari	−£2	£19
Etsy	−£1	£20

Seller-side rates verified 26 Jul 2026 — Poshmark: 20% commission on sales of $15 and above; eBay: 13.6% final value fee, plus a per-order fee; Mercari: flat 10% selling fee; Etsy: 6.5% transaction fee, plus a listing fee and payment processing. Percentages are applied to the sterling figure above; the fixed per-order and processing charges those platforms add are quoted in their own currency and are not included here, so the real deductions are slightly larger. Full breakdown: marketplace selling fees compared.

Timing and getting it to the buyer

Sharply seasonal, April to August, with a small winter-holiday lift. Off-season listings sell slowly.

Tiny and very cheap to post.

WishThrift does not process payments or arrange delivery — you and the buyer agree both directly — so confirm payment has cleared before the item leaves your hands, and keep the conversation on the site so there is a record of what was agreed.

Frequently asked questions

Do people buy used swimwear?

Yes, particularly branded and higher-end pieces. The hygiene liner being intact, an explicit note that it has been washed, and honest photographs are what make buyers comfortable.

What is used swimwear worth?

Typically £8 to £35, with designer and premium brands above. See the swimwear value guide.

How should I describe the condition?

Cover the liner, the elastic and any chlorine thinning. Those are exactly what a careful buyer would check, and addressing them unprompted is what separates a listing that sells.
