Would you wear your shirts off one shoulder?

Gigi Hadid Wears Vivienne Westwood Shirt Off-the-Shoulder With Sister Bella at the U.S. Open

Gigi and Bella Hadid are in town for New York Fashion Week. First, however, the Hadids attended the 2018 U.S. Open to support their friend Serena Williams. On Tuesday night, the tennis champ played against Karolina Pliskova—beating her 6-4, 6-3—as her celebrity friends watched the victory. (Priyanka Chopra, Nick Jonas, Sophie Turner, and Joe Jonas were also in attendance.)

For the tennis match, Gigi wore a Vivienne Westwood striped shirt, teaming it with white biker shorts–her go-to pants of the moment—BaubleBar earrings, and a pair of Dear Frances knotted slides. The model went the extra mile to make her button-down look unique by wearing it off one shoulder. This tried-and-true fashion girl hack is easy to pull off if you don't mind that your shirt looks like it's about to fall off. Gigi's little sis Bella seemed to apply the same styling trick to her own outfit, wearing her dress off one shoulder as well.

After a fun-filled weekend (the sisters spent Labor Day with the Kardasians) and this tennis match, the Hadid sisters will soon be back to work, walking the fashion week runways in New York, London, Paris, and Milan. And if they have time, they might even stop by the Victoria's Secret Show castings, which are happening right now.
