While I can't say that I disagree with anything said so far, Woodsheal made a very good point about a box peat kilt. It seems to me that a box peat kilt would fill a "middle ground" between modern kilt and feilidh beag, and would still look considerably nicer than many other options for most any situation. It's also a historical garment-- in many ways it's more traditional than a modern knife pleated kilt. As a bonus, it would be very convenient, and they are easy to take care of when cleaning or pressing is needed.
