After a day filled with walking in NYFW shows, Hadid wore Topshop Boutique's tie-sleeve, ivory wool coat, pre-tattered T-shirt, vinyl trousers , and Hawk faux croc boots . Now, as soon as the Internet realized that Hadid's exact outfit credits were available at the high-street store, some of the items sold out pretty much immediately. That's the power of an Insta-model for you. Some of these pieces are on the pricier end of the brand's offerings: All together, Hadid's outfit will set you back $742. But that didn't stop shoppers from depleting Topshop's online supply of the most expensive item (the coat) as well as the least expensive piece (the T-shirt) that comprised the model's #OOTD. You can, however, still snag Gigi's rock-and-roll pants, which are a natural evolution of that one Mango skirt we saw all over street-style last season ; or sensible (but stylish) ankle boots — well, if we don't beat you to it.
