Help with unkempt pleats

[Liam]

You can try using a hand steamer if you have one, if not it may cost you as much as you paid for the kilt. Seriously there isn't much you can do.
You can try also pressing it from the inside - that may help a bit. One of the problems with the low yardage kilts is that the pleats aren't very deep and are prone to becoming very wrinkled every time you sit on them. It can help to use a scarf or a belt to hold the pleats in place when you get in and out of a car. Some of what is advertised as wool is a blend of wool and other materials and it doesn't hold a crease the same as wool. True poly viscose seems to be pretty good, but the "PV" from Pakistan has issues. While acrylic doesn't wrinkle and feels somewhat like wool it pills badly and doesn't hold a crisp crease very well.
Just my observations. Take them for what they are worth.
