I'm 169 cm (~ 5'5 ft) and weight about 54kg (~119 lbs)
I usually wear an EU S, but through measuring and previous orders, I usually size one up.
So I ordered a size M. Which was definitely the right choice :)
It fits very well, plus it's not too short. The material is actually nice and kind of thick, though I would've prefered if there was another layer of lining in between. But it ain't bad.
The only "bad points" are: there were some loose threads, the lower part is a bit wrinkled and the "flaps/ straps" on the side stick out a little. But those can be easily cut away and the wrinkles will go away after some time. For the flaps, I simply tuck them in.
Also, something good to know:
It gives kind of a flat chest? xD I don't mind, but maybe for people with a big cup size, it might look weird? I'm not sure :'3
Overall a pretty item. Especially for the fall/winter seasons. Would recommend!
