Whewww this is a beautiful product(even tho i dont currently use it)For me. The shoulder area was a little loose..i ordered a size small. Not sure if any other ladies had this issue but how my body is shaped...im more small up top.There are 3 lines of the cinch(the tiny metal parts you can latch) and this helps you too adjust the mid section as you lose weight.Then the velcro buckle part makes you 'feel' even more supported.For me, this will keep raising as you are moving about through your workout. I was doing step aerobics with 'Xtreme Hip Hop with Phil' on youtube(which is enjoy!) And he encourages and works up a sweat in the participants that my wasit cincher would statt rising up and folding lol. Once i take it off im DRENCHED in the gut area.This is a very supportive amd effective wasit cincher..but if folding and raising makes you irritated...this may mot be for you OR do low impact activities.I wouldnt advise it to wear it all day..but to each their own.
