The All England Club stated that Wimbledon will permit female competitors to wear dark undershorts beginning with the 2019 competition to allay concerns about competing while on their period. There has been pressure on Wimbledon to deviate from their customary requirements that players wear only white attire. As a result, starting the next year, ladies and girls competing in the Championships will have the opportunity, if they so desire, to wear coloured undershorts. It is hoped that by removing a possible source of concern, this regulation change will assist players in concentrating solely on their performance.
