Just received this in the mail, tried it on and am smitten. i'm usually a l, but sometimes i'm a xl (if no stretch), in retailer tops. i bought this one in l and i'm sure glad i did. very flowy, stretchy and comfortable. i also bought the meda lace top from one september and they are very similar expect this is more of a t-shirt and the other is more of a blouse. i almost think i could've gotten a m in this because there is a lot of extra fabric at the chest which is usually never the issue for me
