Leave it to Hailey Bieber to transform the groutfit into the season’s most covetable and copy-worthy look. This weekend, the supermodel joined Bella Hadid at a Pilates class in Los Angeles, where she debuted a monochrome gray fitness look that we’ll be copying for the remainder of winter, both in and out of the gym.

To the class, Bieber wore a gray knit puffer from Prada, which she paired with a matching sports bra, Alo leggings (which just so happen to be on sale right now for under $70), and the New Balance x Aimé Leon Dore 550 sneakers that everyone—and we mean everyone—is trying to get their hands on. She also added a pair of DMY by DMY red-lensed sunglasses and a diamond body chain by Jacquie Aiche. Well, those and a pair of white athletic socks, of course. 

Though this is certainly not the first time we’ve seen Bieber use a workout as an outfit opportunity, it is rare that we can actually shop her look. Hell, even her sold-out sneakers are available in most sizes on the secondhand market. So before this look sells out just like everything else Bieber is spotted in, shop her groutfit below. 

On Hailey Bieber: Prada Wool and Cashmere-Blend Padded Jacket ($2425); Alo High-Waist Alo Soft Highlight Leggings ($68); DMY by DMY Valentina Oval-Frame Acetate Sunglasses ($150); New Balance x Aimé Leon Dore 550 Sneakers ($460); Jacquie Aiche body chain

The coziest. 

If you can’t get your hands on 550s, 990v5s are an equally chic alternative.

These are seriously marked down.

Perfect for the colder months.

Activewear, but make it fashion. 

The only bike shorts you need to invest in.

Girlfriend Collective is a cult favorite in the world of activewear.

This quarter-zip sweatshirt is great for a lot more than just workout classes. 

The extra-high rise on these is super flattering.

The double strap on this bra adds stylish support. 

These are ridiculously soft. 

We love a Skims moment.

For when you’re bored of separates.

These are perfect for every type of workout.
