answer:If you measure your waist (or hips, depending on how low you wear your shorts) in inches, you can probably find a sizing chart on most online shopping sites that’ll tell you what waist circumference the sizes correspond to. Sizes can vary quite a bit between brands. If you can’ t try on a pair that are the same brand as those you want to order, try to find a size chart. Failing that, see what their return policy is before you order, too, to make sure that you can exchange them if they don’t fit.
