Such an original piece. And genuinely looks amazing on. If this is your vibe, snap it up.
It's fitted in the top and waist, with the bottom half being wide leg.
I'd say it is the best fit for a UK10... also, obviously it depends on your body shape, but I'd say it is best suited for those 5'5" to 5'7". The reason being: any smaller and it could potentially swamp you; any taller and the body of the jumpsuit is likely to be too short.
100% polyester. It's lined, but personally I'd cut this out as I think it has a better fit without it.
In fantastic condition.
