In a statement, German gymnast Elisabeth Seitz said: "We wanted to show that every woman, everybody, should decide what to wear."
The subject of women's sporting uniforms has been a hot topic lately, with Norway's beach handball team making international news when they were fined for refusing to wear bikini bottoms.
Other sporting teams have chosen to take a stand against sexist regulations for clothing, including the women of Germany's gymnastics team who are currently competing at the Tokyo Olympics.
