I am 5'8" 155lbs (just had a baby 1/3/11). My normal weight is 136lbs. The Mother Tucker is awesome at holding in my belly pooch and preventing the lovely muffin top. The only thing I don't like is the compression of the breasts. This would be the perfect tank if they would create a looser spandex in the breast area. I ordered a small which I fretted over forever. I went with the small even though I am not currently a size 2-6. I would be more of a 8/10 because of the baby fat in my belly area still. The small is not too tight, it is not too restrictive, I can breathe, move, nurse just fine in it. I don't wear a bra when wearing this tank and the nursing pads stay put great. I hope this review helps someone with questions.
