The supermodel was spotted in the trendy piece during rehearsals with gal-pal and fellow VS model Kendall Jenner.
The supermodel was spotted leaving her apartment in New York City on Wednesday for rehearsals ahead of the show's filming on Thursday in a comfy, sporty look via a bright orange hoodie, dark blue duster coat and navy blue bike shorts by Tna for Aritzia. The blonde beauty unexpectedly opted for black sock booties in lieu of sneakers with a croc-embossed top handle bag.
Jenner looked cool in a black denim cropped jacket, leather pants and square-toe boots, being filmed alongside her fellow models Jasmine Tookes, Grace Elizabeth and Stella Maxwell.
Gigi's sister, Bella, was chic as she headed to the rehearsal in a white top, brown corduroy trousers and chunky lace-up boots with model Cindy Bruna.
