Which Karen Millen pieces hold their value
- Structured occasion dresses with boning and a proper internal construction, which is what separates them from ordinary jersey
- The tailoring — blazers and suit pieces cut with real shaping — which holds its line far better than soft high-street tailoring
- Bandage and ponte fabrics in the signature heavier weights, which are the pieces the brand is actually known for
- Classic black and jewel tones, which are what occasion buyers filter for and which do not date the way a print does
And what pulls the price down
- Broken internal boning or a failed hidden zip, which on a structured dress is a repair most buyers will not take on
- Deodorant and make-up marks at the underarm and neckline, which occasion pieces collect and which must be disclosed
- Loud seasonal prints, which date quickly and narrow the buyer pool to almost nothing
- Altered hems and taken-in seams, which change the fit unpredictably and must be stated with the new measurements
Identifying and dating yours
These are the checks that decide which end of the range a piece sits in, and they are the facts a serious buyer will ask for:
- Photograph the dress on a hanger and flat, since structured pieces do not show their shape properly in one view
- Test and photograph the zip working along its full length, because a hidden zip is the commonest failure on occasionwear
- Give flat bust, waist and length measurements and state any alteration explicitly, with the altered measurement rather than the label size
WishThrift does not authenticate or inspect anything. Condition and origin are described by the seller against five grades — what each one means — so photograph the markings above rather than asserting them.

Frequently asked questions
Is used Karen Millen worth buying?
It depends far more on the line than the label. Karen Millen is an occasionwear label, so its second-hand market is event-driven. Structured dresses and tailoring bought for weddings and parties are what people search for, and they search close to the date. Each guide below says which Karen Millen lines hold their value for that item and which have almost none, so you are comparing like for like rather than paying for the name alone.
How do I check a piece is genuine Karen Millen?
Photograph the dress on a hanger and flat, since structured pieces do not show their shape properly in one view. WishThrift does not authenticate, inspect or grade anything — condition and origin are described by the seller, so ask directly and expect an answer. A seller who has the item will send a photograph of the marking in minutes.
