"We women all want to feel good in our skin. In the sport of gymnastics it gets harder and harder as you grow out of your child's body. As a little girl I didn't see the tight gym outfits as such a big deal. But when puberty began, when my period came, I began feeling increasingly uncomfortable."
Under the rules of the international gymnastics federation (FIG) , athletes may wear a "one-piece leotard with full-length legs - hip to ankle". But it must include an elegant design.
Jamaican gymnast Danusia Francis told the BBC the full body suit "gives the power of choice back" to the athletes.
"I feel empowered that we've got this option where we can choose to cover up," she said.
"We are not here to parade our bodies around - we're here to do sport and be taken seriously".
The sport has been rocked by the recent abuse scandal involving US doctor Larry Nassar, who is now in prison for life after being found guilty for sexually abusing young female athletes.
