I sized down as most of the reviews said sizing was on the big side and it worked! I ordered M when I'm usually L and it fit perfectly!

However, it's a little weird, because the shoulder stitching falls right in the upper middle of the arm (between shoulder and elbow) instead of on the shoulder, which isn't a problem for me ( think it llos even better) but just be warned if this is not something you would like.

Quality fine, washed without any problem.
