I'm a UK 8 for tops, UK10 for bottoms. I've got XS and it looks a bit oversized, I would've love it more in XXS if there was one.
I like the cutting, nice detailing, good sturdy fabric.
I love that the hood is large enough to cover half my face and it's shaped in a way it won't be blown away by a gust of wind.
The only major complain is inner pocket material (photo) is this much much thinner cotton that I suspect it won't last as long as the coat itself. If it was the same coat fabric I would have put more trust to keep my bank cards and keys in them.
