What a used slip 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 slip dresss, so treat them as a starting point and adjust for the specifics of yours.
| Condition | Typical price | What it means |
|---|---|---|
| New with Tags | £50 | Unused, tags or seals intact |
| Like New | £42 | Barely used, no visible wear |
| Good | £32 | Light signs of use, complete and working |
| Fair | £22 | Heavily used, or a described fault or missing part |
| For Parts | £12 | 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 slip dress
- Pure silk with good weight and drape
- Bias cut that hangs cleanly
- Designer and contemporary labels
- Adjustable straps in good condition
What lowers it
- Water marks on silk, which are often permanent
- Pulls and snags in the weave
- Stretched or frayed straps
- Polyester versions sold as silk
How to work out what yours is worth
- Check the composition label for silk content
- Hang it and check the bias hangs straight
- Inspect the straps and underarms
Once you have those three answers you can place your own slip 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
What makes a slip dress valuable?
Silk content, above all. Pure silk holds value strongly; polyester slip dresses sell for very little despite looking similar.
Can water marks be removed from silk?
Often not. Silk marks easily and the damage is frequently permanent, so check carefully before listing.
What is a bias cut?
Fabric cut diagonally to the weave so it drapes and clings. It is what gives a slip dress its hang, and it should fall straight.
