I own three of these camisoles, i first ordered different colors and sizes. I wear them all which probably suggests that the size differences (S and M) are not very big or the S is very stretchy. I don't even know nowadays which size i wear, they all fit me fine. I like the soft fabric, it also hasn't gotten out of shape so far, which can be the problem with those shirts sometimes. The trim on top and bottom is of nice quality. I'm happy with my purchase.
