Sweating side: 10 min elliptical bike and smell sweat. Size side, doing about 42 and I took an S. It is a little tight but after the first wash he relaxes a little. The goal is that it sticks to the skin after all. Anyway I am very satisfied, waiting to see the results of my orange peel. I hope. It is comfortable and very pretty. Odors side: after the first wash it no longer feels the new smell. I recommend it to my friends.
