Hailey Bieber Just Wore This Year's *It* Sneakers With Under-£70 Leggings
Leave it to Hailey Bieber to transform the groutfit (that's fashion speak for "grey outfit") 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 grey 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 grey knit puffer from Prada (nice!), 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 second-hand market. So before this look sells out just like everything else Bieber is spotted in, shop her groutfit below.
