The minute my kilt comes off I open it up and lay it inside out across the foot of a bed, or over the back of a well upholstered chair, with the pleats hanging down. I also turn my kilt jacket and waistcoat inside out (but don't pull the arms out) and let them hang out to air as well. Once the kilt has had a chance to air out-- at least 24 hours-- I place the aprons over the pleats and then fold the kilt in half, length ways. I then carefully lay the kilt in a tin uniform box that has a couple of sachets full of moth balls in it. -- Okay, not everyone has a tin uniform box so I would suggest that laying your kilt in a drawer (or better yet, a cedar chest) would be just as good, and in my opinion infinitely better than hanging the kilt in a closet.

Yes, cedar chests are costly, but if you scout out yard sales and auctions you can usually find them for something in the region of $25-$100-- far less than the $400+ charged in a store.

The advantage of "laying down" a kilt is that it places no stress on the stitching which, in my opinion, probably increases the life of the kilt. Also, it frees up closet space (something that is usually at a premium in most households). This is especially true if you know how to properly fold a jacket as it can also be laid down (on top of the kilt), along with hose, sporrans, etc.
