I agree with bubba, if you're concerned about getting a "men's kilt" you could get a kilted skirt made to knee length out of 8 yards of 16 oz. material. I don't think it'd be too hard for a kiltmaker to make the "kilt" open on the other side.
When I was at the local highland games here in Calgary I saw a lady in a kilt and I will admit it took me aback for a brief moment. I saw her off and on throughout the day and totally came to think it was cool. I think my initial reaction might have been because her fella had a matching kilt on too. haha. Kinda like couples in matching jogging suits.
I'm more of a traditionalist, but I say wear what you want. A heavy weight kilted skirt just might make things... easier.
