I decided to try it out because I wanted an hourglass figure but couldn't achieve it no matter how hard I exercised/dieted. So far its great, the only down side is the first time you try it on, itll be a bit difficult to get it on and it may be uncomfortable. I got an xs and Im 52, 123 lbs (mostly muscle), 27/28 inch waist. I say try it because you may be surprised with the results **Something to keep in mind - some people will say waist training is unhealthy or bad for your organs because it will shift it but if you do your research, it isn't bad if you use it the correct way. Know your measurements and get the right one instead of trying to squeeze yourself into a size that isn't right. Once you get smaller, then move down sizes**
