k-swiss: bondarenkos at indian wells + kournikova at the pop-up store party

The Bondarenko sisters — that’s Alona (the blond) and Katerina (the brunette) — have taken the momentum from their 2008 Australian Open doubles title to make good runs at the Pacific Life Open.

Alona, who’s featured on the K-Swiss website along with fellow tennis players Tommy Haas, Michaella Krajicek, Black/Huber, and Mardy Fish, wore the Empire Seam Top during her three-set loss to Maria Sharapova in the fourth round.

Katerina lost early in singles and wore this dress with an asymmetrical racerback (how very Ukranian of her).

The sisters wore the black version during their doubles win over Svetlana Kuznetsova and Amelie Mauresmo. The duo will face Vesnina and Safina in the quarters.

Buy: Empire Seam Top, purple w/ gold hardware, $48; Racerback Dress, black and white, $90.
