Speedo sizing

Hi everyone, I was wondering if there is anyone who could help me. I swim 3-4 times a week and I have been looking at male swim briefs made by Speedo. I am having trouble with their sizing because thei size charts says to measure 1" above hips bones (or natural waist) but I find it strange because the elastic band of the brief sits below or on the hip bones. I guess my proble here is: my hip bones measure 34" but just above my hip bones I measure 32"!! If I buy a 32", is it not going to be a little tight for me when the briefs sit on my hip bones? In a swimwear store I was told to always buy a size above my usual pants size (which is 32"). Any advice would be greatly appreciated. thanks a lot, JM
