This didn't fit me as tightly as I would like in the waist, which is surprising because I am not slim. This isn't very flattering and lets water pool there and be cold, which is uncomfortable, but can be got around by wearing a pfd belt or shorts over it. Good quality and comfortable, surprisingly warm. Except for the waist gap, it's a pretty suit. Maybe if you were a bit straighter in the hips than I am it would do better. (I'm a bit curvy, albeit in a fifty-year-old, no longer in all the right places sort of way and I may be a bit long-waisted, which maybe kind of causes it to \"tent\" from the bump of my considerable backside to my shoulders.) Or, if you're a bit thicker in the waist? Either way, feels good, and with something around the waist to pull it in, it looks good too. I'm 5.7, 186lbs, usually wear a size 16 jeans. (16 was too short in this, couldn't get it up over my shoulders, so I got the 18.)
