A Little Bit of Advice Requested

... Yes sir. Turn them inside out, run a beeswax candle down the crease, then right side out and press. ....

We used to use the same method but with Pritt Stick instead of beeswax. Worked a treat for getting a lasting crease down the sleeve of you Jersey Heavy Wool. Not sure about using it on kilts though.

Jordan, I think it might be worth your while phoning the local kilt rental shops and asking what they do with kilts returned in poor condition. I think they will use professional cleaners, or they may do it in-house, either way they will no doubt have dealt with kilts which have sadly been on the receiving end of treatment like yours was.

Anyroad... back on track.
I'd try Gingerpose's plan Jordan. Although you might need to explain exactly what you want. Can't imagine wide boxpleats are that common where you are.

Would suggest steaming it while hanging with a portable steamer - available at any big box store.

My optimistic guess is the steam would undo some of the flatness, fluff out the material a bit...

Or just hang the kilt in a steamy bathroom for as long as you have steam from the shower.

A quick update i went to my local-ish kilt hire shop today to ask about my kilt and the guy there says they do theyre own kilts and he wouldnt know how to fix mine unfortunatly.
