Bought in both the black and white ... because these are the underpinnings of so many different looks. For sizing, I normally wear an X. I bought an X, even though the Additionelle stuff can run a bit skimpy. 42" bust - 5'6". Fits like it was tailor made for me. Long enough to wear over leggings. Armholes cut so that your bra won't show. Enough ease for the girls to be comfy. Nice material that washes like a dream and hangs to dry. Love these end of season sales for stocking up on the classics.
