I'm tall (6' 2) with a small waist (32) and a big chest (44). I chose the size that fit my chest and the rest worked fine. The pants were too short, so I went out and bought longer stockings. Also, if you're heavy the belt might be too small. It fit me, but a fat person might have trouble with it.

Overall the quality was great and we bought 4 for a parade. We loved them!
