The first belt I ordered was a large, which was clearly too small. (38 to 44) My kilt size falls between 47 and 48. So, my size 48 is a bit loose. But the belt sizes from Scottishkilts.com aren't listed by number size, only small medium largs and extra large. I figured I could order some leather working rivets and move the buckle to make it fit. But in the neantime, I ordered a new belt in extra large. (45 to 50 on the underside of the belt). The extra large is too big, so I'm going to have to modify that one also. I guess I'm either going to have to gain some weight or lose some. But if I lose, then my kilt will be way too loose, so I guess I need to gain an inch on my waist. I definitely don't need the low carb beer.
