I think gymnasts get points deducted in competition for having any line under their suits, so can't wear bras as well as pants.
The first time I went to a children's gymnastics competition was to watch a friend's son. I felt really uncomfortable with what the girls were wearing. I felt embarrassed actually to be an adult watching preteen girls doing the splits etc. in such skimpy clothing. I'd never seen gymnastics off the TV. Nobody was perving, but it just didn't feel right. I think the girls should wear what they want but the question isn't that, it's why would adults want to watch girls in such little clothing? However, it's even a hard question to ask because there's an implication that everybody watching is perving. I don't think they are at all, I think that you just get totally used to seeing leotards and don't see it with fresh eyes.
For every gymnast on TV, that are literally thousands of girls on a Saturday morning turning up at local gyms for competitions. They're mostly all wearing leotards and have no alternative if they want to keep doing their sport. It's actually ridiculous.
I hope this really opens the way for gymnasts, most of whom across the sport are under the age of consent, to wear something else.
When I saw this news last night, there were lots of supportive comments under the article, plus a sizeable amount by men saying "No point in watching anymore if they wear this". Now, if I were organising a sport at a national level and knew men were watching it for sexual thrills, I'd be wanting to make sure my sportswomen (and girls!) weren't being used sexually, even indirectly, to increase revenues, but were instead being viewed for their talent and skill.
