I have several kilt hangers of various designs as well as several pairs of the two-hanger type that my kilts are all hanging on, and all my kilt jackets as well as my winter wool regular dress coats are all in plastic hanging garment bags with either cedar blocks or lavendar scent dispensers (actually supposed to work as well as cedar without the strong smell, as long as you like lavendar smell). Keep my hose and caps and all in a sealable plastic storage container with a few cedar blocks too. I have some extra closet space in a spare bedroom that is my "kilt storage and collection" facility to please my wife, who does not like seeing it every day in our regular walkin closet off the master bath.

I can really recomend the lavendar dispensers (look kinda like moth ball holders but the smell is much more pleasant than either mothballs or cedar).
