We recommend you measure your favorite belt for the best fit. If you can not measure a belt, we suggest adding 4 inches to a man's pant size to obtain the best sizing. For example, someone who wears a size 34 pant would wear a size 38 Bluegrass Belt. When the waist is an odd size, increase the belt size by 3 inches (i.e. a size 33 wears a size 36 belt). Please your own discretion when choosing a size.
