Please be very careful when choosing your dry cleaner. Most have never seen a kilt before and do not have the fainest idea how to properly press a kilt.
Horror stories abound.

If you wish to have your dry cleaner do the job I strongly suggest you baste the pleats first.

And by all means, if you have an acrylic kilt, WARN THE CLEANER FIRST! Getting back a ball of goo that used to be a kilt before being soaked in some cleaning solutions can be quite a shock.
