I love this co-ord set... in fact I am loving co-ords generally.
A good fit for a UK8 - smaller UK10 (key is that you have a relatively small waist). The fit is oversized. The shorts are fairly snug in the waist (a bit too snug for me and I am a pretty standard 10) and sit on the knee in length, based on a height of 5'7".
So the fit is: small waist, slightly oversized elsewhere.
The colour is a slightly purple blue.
In excellent vintage condition. There is a tiny mark on the he m of the shorts - please see final photo. This is not noticeable at all when worn.
