The sisters earned the ultimate high-fashion stamp of approval in the form of a red-carpet selfie with creative director Olivier Rousteing.
Unfortunately for the Siberia-born sisters, the rest of their trip to London will be one to forget as both went out before the second round in singles.
Erika, ranked No. 101 in the world, fought through the qualifying rounds to reach the main draw for the first time in her career. But she came up short in the second round against Donna Vekic, who eased to a 6-2, 6-3 win on Court 9.
Mirra, sitting at a new career-high ranking of No. 23, reached the fourth round last year in an unforgettable Wimbledon debut. But she couldn’t recreate the magic this time around, stunned in the first round by the even younger Brenda Fruhvirtova, 17, falling to the Czech 1-6, 6-3, 6-2 on Day 1.
