The more informal way of sitting (and this is more proper for women, but I'm sure it doesn't really matter; it's also more comfortable for those not used to sitting in seiza) is cross-legged, with your knees and feet in front of you. The way I get into that position while kilted is to kneel, then lean to one side and sit, so both legs are to one side of me, then lean back a little bit and cross my legs while holding the apron down in the middle. I've done this innumerous times in informal settings, and have never flashed anyone. A better way for those with more flexible knees than I have is to simply lower yourself into a cross-legged sitting position from standing (while standing, cross your ankles, then slowly squat and sit behind your ankles). Just hold your apron down, and try to do a butt-sweep for the pleats at the same time!

Personally I stick to restaurants with Western-style seating at tables because it's just too darn hard for me to get down and up from floor seating because of my leg.
