Don't many fencing jackets have a groin that straps between the legs to connect with the back? I know a sabre jacket (especially a lamé jacket) is cut to the waist, but the regular protective jackets drop lower. Those definitely wouldn't work with a kilt.

You certainly woud be able to lunge easily, but I think a stray thrust could get tangled up in your kilt and be a danger. Besides, you'd have to find an all-white kilt and match that with white hose and flashes, and a white sporran.
