I bought the white in a m, one size down from my normal. i could have gone with a s, given the swingy shape and forgiving nature of the linen. it is very light and comfortable. the length is a tunic on me, at 5'6", so keep that in mind. if you dry it in the dryer it will shrink for sure. i never recommend drying linen knits in the dryer because they will likely develop holes. i love this tank and will probably buy another color or two. if they get black or grey i will def. buy another one.
