In my case, I have two kilts.One semi-traditional and one 5 yard both made by Rocky at USA kilts. I measured by his instructions and decided the length should be 25 -
25 1/2. I decided on 25, but my second kilt I went to 25 1/2 for the length . Better to be a little to long, than too short.Use a large beach towel and fold it the different lengths to see what it might feel and look like. I will have any future kilts made to the same measurements so hopefully I will stay at the same weight. I don't know what vendor you have picked but Rocky's customer service is second to none. Good luck.
