I was a bit hesitant after reading some of the reviews about the thinness of the top. It is thin, but not see through thin. Of course I got black, can't speak for the lighter colors. And I haven't washed it yet as I've only had it a short time. It fits perfectly! I can't count the number of times I've ordered a similar blouse and the arm were too tight or it had a baggy shape, or something! I'm 5.6" and weigh 110 and the medium was perfect. A small might have worked, but I just can't stand constricting clothes, so it's great.
Speaking of constricting, a man must have invented the bra. I don't have a lot to constrict, but talk about uncomfortable. When I get home, it's the first thing to go, after shoes...sometimes before!
Back to the blouse, I'm here to order another. Love the 5% back and the free shipping and NO taxes. Best $** spent in a long time. And I've seen deals off the yearly charge also. Do yourself a favor; good buy. And the shipping was almost as fast as from you know where.
