I'd support the Kathy's Kilt suggestion. Just dealt with her ordering my clan tartan kilt. My waist is a 46" at the naval and we talked through how she was gonna work with that...I wear my non traditional kilts under my belly where I'm 42".

Point being, she didn't seem to miss a trick in figuring out the sizing.

The other thing about Kathy, besides her training in certifications from Scotland, is that she'll be the one actually hand sewing the kilt so there's no need to pass on the instructions.

You've a situation there that brings to mind the old adage, "you can measure a thousand times, but you can only cut once."
