This is the third time I buy this garment. It is the most comfortable one I have found (and I have used many), while at the same time providing support. It is not supper tight, which I do not like, but it still flattens the tummy and smooths the bulges; but no, it does not make one look one size smaller. I am 5"1', weight 140 pounds, and I can use either the M or the L. The M is tighter, and the large still works, but is more comfortable; easy to wear all day long. The material is thin and, I would say, breathable, so it is surprising that it still provides good support. I do not have any problem with it being tight at the legs or at the shoulders. On top of everything the price is extremely competitive compared to similar items on the market.
