Just picked up a really nice WWII era Blackwatch tank off of eBay. It was advertised as a 34" waist, which would have been ok for my 36" waist. Come to find out, it's actually more of a 31" waist which makes it near impossible to buckle. Without knowing much about kilts, I've noticed on this particular kilt that the edge of each apron is taken-in/folded & sewn about two inches on each side. Do these folds serve a particular function or can/should they be let out to allow more room if the proper buckles and straps are moved to accomodate the additional material? Any help would be appreciated.
