Before I acquired a proper kilt, I wore a woman's kilt with the closure flipped. You have to cut a slit in the waistband to allow the "backwards" closing and the best thing is to bind that, to avoid fraying. Careful Kilt Detectives will espy an extra pleat or two at the front ( port and starboard bows, or app 10 and 2 O'Clock) but most observers will not know the difference.

I am surprised nobody has mentioned the various tartan finders which allow reverse lookup of pattern. They may help you narrow down the candidates, though you may well have a "fashion tartan".

Welcome, regardless.
