The short version
- Typical range: £3 – £15 — see the full baby grow value guide
- What decides your price: condition, and how well you evidence it in photographs
- Cost to sell here: nothing, at any price
- Category: Baby & Kids Items
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.
- Wash everything and check for the marks that do not come out: weaning stains at the neck and cream stains at the legs.
- Sort strictly by size, since parents buy by age band and mixed bundles sell for far less.
- Check every popper and zip, and the elastic at the cuffs and ankles.
The photographs that sell a baby grow
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.
- The bundle laid out flat together, countable
- A representative garment front and back
- The size labels grouped together
- Any stain, bobbling, or stretched popper, close up
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 It feels counterproductive, but a listing that shows the worst of an item gets fewer questions, fewer withdrawn offers and fewer arguments at handover.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
Size, quantity and brand: “10 Baby Grows, 3-6 Months, Mostly Next, Excellent Condition”. Age band and count are the searches. Naming the brands lifts a bundle noticeably, since parents recognise which wash well.
Then state these in the description, because a buyer who has to ask is a buyer who might not bother:
- Age band and how many garments
- Brands included
- Whether long or short sleeved, and whether integral feet
- Honest condition, including any stain, bobbling or loose popper
What buyers will actually ask
You will receive the same three messages about a baby grow. 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.
Check the neck and legs specifically and say. Parents are realistic about baby clothing, but a bundle described as excellent arriving marked is a genuine complaint.
Give the age band from the label, and note that sizing varies by brand. Newborn and 0-3 in particular differ a lot between makers.
Say so plainly. For baby clothing that single line does more for the listing than any photograph.
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 baby grow 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 £9 sale — roughly the middle of the range for a baby grow — 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 | £9 |
| Poshmark | −£2 | £7 |
| eBay | −£1 | £8 |
| Mercari | −£1 | £8 |
| Etsy | −£1 | £8 |
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.

Timing and getting it to the buyer
Steady year round. Bundles in popular sizes sell within days because parents buy in quantity and constantly.
Very cheap to post and bundles cost little more than singles — which is exactly why bundling is the right approach here.
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
Are used baby grows worth selling?
In bundles, definitely. Individually they are worth less than the postage, but ten in one size sells readily because babies outgrow them faster than they can wear them out.
What are used baby grows worth?
Typically £3 to £15 for a bundle, with premium brands above. See the baby grow value guide.
Should I mix sizes in a bundle?
No. Parents buy for the size their baby is about to be, and a mixed bundle is worth less than two single-size ones. Sort strictly by age band.
