We have a guy on our adult synchro team. Be sure, we tease him, and threaten sequins, ruffles and all sorts of wonderful things, but when it comes to it, he wears the normal black pants and a shirt that goes with our dresses. But he's really good natured about it, teases us right back, and is always ready to throw on a wig when its appropriate (and yes, it is appropriate more often than you might think!!) and goes for it. Especially for the end of season show, he often has special roles to play, and gets to take center stage, I think more often than he'd prefer, but he goes along with it. Just like anyone else on the team, he's an integral and respected member. If he's uncomfortable with something, either outfit, choreo, theme, whatever, he speaks up. We don't ask him to do things outside his comfort zone.
I know when there was a Sr team, there were a handful of guys who skated on it. From what I can see of past outfits, they also did the black pants, and a co-ordinating shirt, nothing too outrageous. Johnny Weir would be disappointed.
Hopefully this is how it is everywhere, especially on the recreational level teams (if you're going to eventually skate for the Haydenettes....that'll be another story). I would say go for it. I love synchro, having the team comradarie takes skating to a whole new level.
