When Gigi Hadid stepped out in New York, she might have been wearing all black — save for her charcoal skinnies and a flash of gold on her studded boots. But Gigi looked sleek. "What, like that's hard?" you're probably thinking of the style savant [1], who can make any casual ensemble [2] look elevated and cool. Lucky for us, the key to nailing the supermodel's most recent outfit, consisting of a baseball cap, a slouchy sweatshirt, jeans, and flats, is in the fabric of her pieces.

While you could opt for a cozy top in a jersey material, Gigi proves that choosing satin separates makes all the difference. Though her baseball cap may be on backwards and her sleeves pushed to her elbows, Gigi's high-fashion sense [3] is obvious — and especially easy to re-create. Read on for all the inspiration you need, then shop for a matching hat and crewneck with luxe little details like Ms. Hadid's.
