According to Golf Digest, LPGA Player President Vicki Goetze-Ackerman sent out an email to golfers on July 2 informing them that the dress code would be changing as of Monday, July 17. Goetze-Ackerman ticked off the items the women would no longer be able to wear on the green, including plunging necklines, joggers, leggings by themselves (they can be worn under shorts or skirts), and racerback tops without collars. "No collar = no racerback," is the parenthetical used in the email.
