I bought this one and another one in a different color (both in M). Anyway I absolutely love them. The fit is PERFECT for me and I hope they come out with more colors. Material is soft. Love them.
The fabric is soft and smooth and comfortable to wear. I don't know if it will wrinkle if I don't wear it a few times, but it was more than I expected. I ordered one size larger, so it was a little big, but it's soft to begin with, so it's totally fine.
