If you lay the kilt out on a table it should be fairly easy to straighten the pleats top to bottom. If they are badly splayed you may have to pin them in place before you baste them down. Once they are basted you can stream press then back into shape. Spray the kilt with water - use a pressing cloth - and be sure to PRESS the pleats down - no back and forth action. It may also be necessary to flip the kilt over and press the inside as well.

If you have a trustworthy drycleaner - they may be able to press the kilt after you get it basted back into shape.

Heck Turpin - anyone that can make such beautiful sporrans should be able to re-press a kilt!

Good Luck!
