May the 4th be with you (but not overwhelm).
Americans can go a little nuts with the clothes over 4th of July weekend. If you simply MUST wear red, white and blue on court keep it classy with a very light dash of Old Glory.
Above, Annika has added the Spirit wristband by Wristpect, a headband by Sparkly Soul (love these) and a super summery red, white & blue canvas tennis backpack by Ame & Lulu. So sharp over a bright white base. It's Wimbledon finals weekend after all and we mortals CAN do color.
Tennis shoes? White works well of course but colored shoes are much more fun so push it in the hot looking MC 996 by New Balance. Girls, buy 2 sizes down.
