I am 5'7" or so and usually wear a 6 or 8, and a Medium in tops. I ordered a Medium in this sweater and it was huge on me. I realize this sweater is supposed to have a bit of a slouchy look, but this was too much. I wasn't crazy about the fiber composition eitherit has some acrylic and lurex in it which I thought gave it a cheap look. Otherwise, I liked the color and the concept, but not the fit or the price for the fiber quality and look. I returned it.
