I bought based on the measurements chart...but had to order a second time (and pay for shipping again, since I'm in Hawaii) because I definitely needed to size up! With the correct fit, these shorts are great! They feel good, they don't move or ride on me. Plus they are cute and when you look good, you feel good!
The waist band could be a little wider. Sits a little low rise than my older Zoot shorts but they look great. First race with them will be this weekend. Padding is very minimal but enough for a 70.3.
