I can only imagine that some schools have more “risque” outfits. Our high school has an extremely conservative looking cheerleading outfit and pom outfits. I watched a game last night... the cheerleaders were very appropriate and downright cute. The cheers were “old fashioned” type... (and this is a public school in a very populated area).
I don’t doubt some schools do have more risque outfits - in fact I know they do - fortunately, ours isn’t one of them. And they’re good at what they do and have the trophies from competitions to prove it.
My daughter does dance, but never showed any interest in cheerleading, but several of her friends were on the squad in middle school and all but one were in the same advanced classes as she was. They all start HS on Tuesday - I’ll be interested to see which of them decides to continue with cheer.
