I wear pants/shorts with a 34ft waist and order the big ones and everything was fine. There is also significant stretching. I wanted a summery golf belt that could be worn with black moccasins, gray pumps and white golf shoes. It's perfect for all three. A similar Peter Millar belt is $150(!) at my club's pro shop, while the Mill River (member discount price) was still $80. The best purchase I've made in a long time.
