'Legendary' hidden detail spotted on Simone Biles' outfit

Simone Biles is widely regarded as the greatest female gymnast of all time and the American superstar is not afraid to show it.

The 24-year-old has for years defied what most thought was possible in the world of gymnastics and she did it again over the weekend after becoming the first woman in history to land one of the most dangerous tricks ever conceived.

Competing at the US Classic in Indianapolis, Indiana, Biles successfully attempted the notorious Yurchenko double pike in competition, leaving the gymnastics world in awe.

The Yurchenko double pike, featuring a round-off onto the springboard and back handspring into a piked double backflip, had never been done before in women's competition.

The fact that Biles even attempted it - let alone landed it - merely cemented her status as the greatest of all time (or GOAT) in women's gymnastics.

That reputation is clearly something Biles has no problems promoting herself, as evidenced by the outfit she wore at the meet.

Admittedly, not much of the focus was on the leotard the four-time Olympic gold medallist was wearing as she sealed an incredible piece of gymnastics history.

However, eagle-eyed viewers noticed a brilliant detail on the back of the outfit - a rhinestone goat's head - that shows what Biles thinks about her status in the sport.

American explains extraordinary trick

Biles explained her thought process behind the incredible vault after sailing through it with so much power that she over-rotated slightly and stepped back on the landing.

"I was just thinking, do it like training," she said of her mindset as she took off down the runway.

"Don't try to overdo anything, because I have a tendency as soon as I raise my hand to kind of overpower things.

"I did a little bit, but at least I still was on my feet and it's a new vault."

Footage of Biles completing the vault in training this week had set social media ablaze.

"It's nice to see all the support," Biles said, adding that she was "feeling confident" heading into the US championships from June 3-6.

That will be followed by the US Olympic Trials from June 24-27, where the top two finishers will book Tokyo berths, along with two other gymnasts named by USA Gymnastics selectors.

Although Biles wasn't perfect in her routine over the weekend, she still won the all-around competition with a score of 58.400, with Jordan Chiles second on 57.100 points and Kayla DiCello third on 56.100.

It was a triumphant return for Biles, who will attempt to become the first woman to win back-to-back Olympic all-around gold medals since Vera Caslavska in 1964 and 1968.

"I'm just happy to be back out here on the competition floor in an arena with all of the girls, especially after the long year and time off we've had," Biles said.
