I think it's great there is an option for dress.
There should always be an option to decide how much body you expose.
I don't agree with the over sexualisation. There is undoubtably been issues with inappropriate coaching in the past and I know gymnasts are speaking out.
But many prefer the leotard and should have the option to continue to wear it.
Same as athletes should have the option to chose shirts or bikini style race shorts.
Just this week we've had the handball team wear shorts because they want to (I support this) but also the para Olympian complain because she was told to consider a fuller brief to run in.
Personally I find it horrifying that in 2021 we are still commenting and putting limits on what woman wear.
