Girls trampolining and leotard glue AIBU to be shocked

[rookiemere]

So my friends 10 yr old DD has taken up trampolining. she's showing great promise and is competing already. However I was totally shocked when she told me that they aren't allowed to wear pants and therefore have to use leotard glue to keep it in place. They are also not allowed to wear bras. Boys who do the same routines wear tracksuit bottoms.

AIBU to think this is a sexist outmoded practice and actually a bit creepy?

I'll never forget the humiliation of doing gymnastics as a pre-teen going through that awkward phase of puberty and some white discharge (sorry for tmi) soaked through my leotard and some of the nastier girls saw it and started laughing and told everyone blush knickers are a must!
leotards have gussets like pants with a kind of meshy absorbant fabric I am really surprised that discharge would leak through this
My DDs used to just wear a tampon when they were on their period and sometimes a flesh coloured leotardy undergarment.there really is no need to take hormone pills, unless you have an abnormally heavy flow

There was definitely more coverage for women in Olga Korbut's time. Not a buttock in sight here. I don't see any reason why they need to be so skimpy.
