The fabric is very thin, it can't get any thinner, I can't imagine someone being able to wear it in the winter in cold weather even though I haven't tried it yet. Good fit at the waist except for the length. I am 1.85 meters tall and wear a size Large, the jumpsuit was way too long, there is too much fabric hanging down at the bottom, it folds and doesn't look nice. I had to take it to a tailor. The fabric may feel a bit cheap at first touch since it's polyester, but visually the jumpsuit is quite aesthetic.
