Please check the profile, just in case. I think I bought this at ZARA two years ago. I wore it only once and then forgot about it. It's been sitting in the closet ever since. It's a size S, but it runs large! I think it can be worn by people who usually wear M or L sizes. This shirt doesn't have buttons all the way up! It's the type of shirt that's meant to be open at the chest, so please wear an inner layer that you don't mind showing! The fabric is sturdy and thick for a shirt, so although there's some exposure at the chest, it feels secure. Please iron it before wearing.
