If you're wondering how to pack a gym bag, Gigi Hadid can show you what to wear post-workout. After hitting the gym in New York City on Sunday, the supermodel knocked out errands, including a grocery trip to Whole Foods, while mixing upscale outerwear with the Adidas sneaker trend.

For her busy afternoon, Hadid wore a structured black longline coat, her own cashmere brand, a guest-in-residence red cardigan, and a white T-shirt. She also mixed in some workout staples, such as black leggings peeking out from under her buttoned-up coat. She also tied the look together with bright cherry red Adidas sneakers and slouchy crew socks.

Accessories didn't end with Hadid's three-stripe sneakers. (Kendall Jenner, Harry Styles, and Olivia Wilde are also known fans of brightly colored Adidas gazelles.) The 28-year-old also chose an off-white baseball cap by Virgil Abloh, a mini bowling bag by Miu Miu, and oval sunglasses. Her picks. In the extreme cold winds, she kept extra warm with sleek black leather gloves to hold her Whole Foods grocery bag.

Hadid has long elevated the casual silhouette, but only recently has she maximized the potential of black leggings in a photogenic way.

For example, last week's outfit: on a March 14 outing to NoHo, the supermodel paired a baggy T-shirt and black blazer with her trusty athletic bottom. Along with a Miu Miu bag and black sunglasses, she added a chic touch with chunky loafers and scrunchy white socks.

Hadid's Sunday errands followed a jam-packed weekend spent with boyfriend Bradley Cooper. The couple made several appearances over the past few days, opting for late-night dates in New York City.

The two kicked off the weekend with dinner at Cucina Alba. As they left the Italian restaurant, Hadid traded her leggings for baggy blue denim. She wore a black V-neck sweater and a white T-shirt with a leather jacket and leather pointed boots to complete the look.

The following night, Hadid and Cooper were seen leaving the Broadway play Sweeney Todd: The Demon Barber of Fleet Street. There, the supermodel wore a mostly neutral palette, with a cream top, caramel brown cardigan, and matching gingham pants. She added a soft color contrast with a black leather jacket, a Miu Miu mini purse, and black boots.

Hadid has a knack for turning a simple outfit into a no-mistake fashion statement, whether she's heading to the gym or going out for the evening. Her off-duty style proves once again that sticking to the basics can sometimes have a strong impact.
