West Bromwich Albion women will wear navy shorts with their home kit because of concerns about having to wear white while on their periods.
Wearing white can be a cause of anxiety for athletes on their period with worries about leaking on top of any potential physical symptoms.
"It's great that the club are supporting our change to navy shorts," captain Hannah George said.
"Representing the club professionally and looking smart in the kit is really important to us.
"This change will help us to focus on our performance without added concerns or anxiety."
Many sports traditionally wear white clothing, such as tennis at Wimbledon and Test cricket, with the dress code the same for both men and women.
