Great training suit, would have prefered mesh on both sides as is implied by the "reversible" adjective.

waist line is true to the sizing scale... so a 28 fits a 31 to 32 waist.  Only 2 issues I had with it but for the most part really like it.  1.  The leg openings are pretty tight, and my legs aren't even that large.  2.  Make sure you really use the drawstring otherwise it can very easily move down a little bit lower and show off a little 'crack' in the back, but I found by making sure you get it where you want and then tie the cord it stays where it needs to be.  Make sure to put this on with a mirror around to double check lol.

fits a little tight on the legs

none

We bought one size down because we were told they run big and that worked well.  Holds up well and does not become distorted from repeated use in the pool.  The reversible quality is a nice option.

I THOUGHTH THESE WERE GONIG TO FEEL PRETTY UNCOMFORTABLE BUT IT ENDED UP THAT THEY FELT JUST RIGHT. REALLY GOOD. LOVED THEM.
