I am a size 8 or slightly larger, so although I often do use Ms from BCBG in this case I ordered the L. It is perfect. Smooth, svelte, able to be dressed up or down. My preferred style is comfortable but classic, able to go anywhere, and this fits the bill. It's very nice, and although slightly sheer it it's thick enough and not "Too" sheer. Highly recommended.
