Well, in reply to okgo's question about tights, I wasn't embarrassed, I didn't even really think about it... though I was a bit embarrassed when I realized that wearing boxer shorts under the tights was making them crease, wrinkle, and set weird. Mainly though, since I started in a class that was comprised entirely of middle-aged women (including the teacher), except for my fellow ballerinos (that's a male ballet dancer, for anyone who doesn't know. I guess I might not have to explain that here though...), I was more concerned about learning the steps. The most concerned I get about the tights thing is whether my jock-strap (I use a jock-strap instead of a dance belt because I haven't bothered to figure out the sizing and everything. It's probably quite simple, but there's not like the things are returnable, and it's really no difference, other than color) is making visible lines under my tights. All in all, I really don't mind the tights, except for the white undertights: I wear "cool" pants over my tights, and they're generally baggy enough to cover the tops of my shoes, but when I'm biking to class or when I'm wearing my favorite pair of the things, which are slightly torn around the cuffs, I tend to wonder what people think about "socks" that go past my middle-shin.
I guess this reply is a little late, but I just discovered these forums tonight, so... I just thought I'd weigh in on the off-chance that anyone cared.
