Gigi Hadid rules the runway.

So the 21-year-old beauty wasn’t afraid to break a fashion rule or two Sunday in NYC, when she stepped out in clashing stripes and a haphazardly styled blouse.

The IMG stunner looked laid-back while keeping her breezy dress shirt unbuttoned to expose her smooth chest and sultry cleavage.

Rulebreaker! Gigi Hadid wasn’t afraid to break a fashion rule or two Sunday in NYC, when she stepped out in clashing stripes and a haphazardly styled blouse

The girlfriend of Zayn Malik combined a striped button up with loud striped trousers in a red, creme and black pattern which also featured leather knee-pads.

Gigi tucked in one side of her striped shirt while letting the blouse billow open to reveal a glimpse of her black bra and Victoria’s Secret famous cleavage.

The Tommy Hilfiger muse topped off her look with a messy ponytail, small oval sunglasses and suede ankle boots.

Gigi – full name Jelena Noura Hadid – started off the day on a healthy note.

Usually the VIP, the 5’10.5″ beauty was the one seen carrying a tray of green juices while donning a dark smock.

It turns out the elder sister of Bella and Anwar was doing a photoshoot for Juice Press in the Tribeca neightborhood of NYC.

Showing off her pencil-thin legs from beneath the knee-length outfit’s hem, she’d pulled her hair back and tied it into a ponytail, accessorizing with hoop earrings.

Crew members were seen thronging about the Instagram dynamo as she stepped outside through a massive open door, her slicked-back hair tucked behind her ears.

Gigi first gushed about the organic juicery in a Vogue Australia interview back in 2014, telling the fashion glossy ‘I’m a really big Juice Press fan. There is a store right around the corner from my apartment in New York.’
