I say go for it. Get the tartan you want , get a traditional kilt. Wear it with a bulky sweater... Heck you have your own fashion sense. Don't worry about which way it closes. That's for a time when women had dressers and it was convenient for the dresser to dress you.
I think, once you have one you will find occassions to wear it. If it get's dirty it can be cleaned.
Wear it with pride.
Cheers
