Every season, there tends to be one item from Zara's collection that emerges as the clear stand-out. There's usually little room for debate as to what the winning garment is: You'll know as soon as you spot it on every other person you run into. (And if most of your friends aren't already in possession of said item, they're probably en route to purchase it.) We may be getting ahead of ourselves, but we might've just found the fast-fashion retailer's breakout hit for summer '17 — and that's all thanks to Bella Hadid.
