Until recently there were "Bloomers" or tennis underwear that women wore under skirts but over their traditional underwear. The majority of these had elastic ball pockets on the back side that women put their extra ball in. Newer tennis skirts have spandex athletic shorts built into the skirt. Some also have ball pockets, however, most women simply store the ball up the leg of the shorts.
