What a used prom dress is worth by condition
Condition does more to the price than anything else. These figures are worked from the top of the range for prom dresss, so treat them as a starting point and adjust for the specifics of yours.
| Condition | Typical price | What it means |
|---|---|---|
| New with Tags | £120 | Unused, tags or seals intact |
| Like New | £102 | Barely used, no visible wear |
| Good | £78 | Light signs of use, complete and working |
| Fair | £54 | Heavily used, or a described fault or missing part |
| For Parts | £30 | Not working or incomplete, sold as seen |
These are the five grades WishThrift listings use, and sellers set the grade themselves — see what each condition grade means. Figures are shown in pounds as a reference point. On WishThrift prices display in your own currency, and sellers set their own asking price.
What raises the value of a prom dress
- Designer and boutique labels with a following
- Worn once with no alterations cut in
- Sizes across the full range, not just the smallest
- Listing in the run-up to prom season
What lowers it
- Hem marks and dirt from the night itself
- Alterations that cut fabric away permanently
- Broken zips and missing beading
- Listing well outside the season
How to work out what yours is worth
- Check the hem and underarms in daylight for marks
- Note the size as altered rather than the label size
- Photograph any beading or detail close up
Once you have those three answers you can place your own prom dress on the table above with reasonable confidence. If it sits between two rows, price it toward the lower one — items priced honestly sell faster than items priced hopefully.

Frequently asked questions
Do prom dresses sell well second hand?
Yes, reliably. They are worn once, which means most are in near-new condition, and buyers actively look for them to avoid retail prices.
When should I list a prom dress?
In the months leading up to prom season. Demand is strongly seasonal and prices reflect it.
Does an altered dress still sell?
Yes, but state the actual measurements rather than the label size. Alterations that cut fabric away narrow the buyers it can fit.
