First, , I would measure at the navel. But there are several different styles of kilt, worn in a low, medium or hi rise to the waist. What type of kilt were you going to try? Several members will say try the x-kilt for your first kilt, I agree. The instuctions are very straight forward. They are in the DIY forum. Again welcome and don't be afraid to ask, but do watch out for falling puns and such.
