I really like this top. I got an XS and it is true to size. The material is stretchy so the shirt is form-fitting (which I like). I only wish that the sleeves were a bit shorter- the length isn’t very flattering, but I just roll them up and it looks great.
Rated 0 on a scale of minus 2 to 2, where minus 2 is Runs small, 0 is True to size and 2 is Runs big
