I don't know about you, but when I wear leggings, it's usually with other laid-back stuff, like a sweatshirt or a crewneck. Nothing too fancy, and certainly nothing luxe. So when I saw Hailey Bieber's latest gym look, which included ultra-cozy leggings, a sports bra, and a $3,700 designer puffer jacket, I was intrigued.
Bieber wore the Alosoft Highlight Leggings from Alo Yoga, the unofficial leggings brand of supermodels. (Case in point? Bella Hadid was right by her side that day, also wearing Alo leggings, but from the buzzy Airbrush collection, my personal favorite.) Bieber's Alosoft leggings are made from a second-skin performance fabric that does it all: shapes, wicks moisture, and moves with you thanks to a four-way stretch construction. But perhaps the most important thing to mention is how comfy they are.
In their reviews, Alo Yoga shoppers are crowning the Alosoft pair "the softest leggings ever." In fact, nearly every review mentions something about the ultra-cozy texture. But really, that's no surprise, given that "soft" is in the product name.
Bieber wore the beloved leggings with a matching ribbed sports bra that's currently on sale for $41 and a $3,700 gray Prada puffer coat in an example of high-low done right. She finished off the look with a rare pair of New Balance x Aimé Leon Dore 550 sneakers that everyone is trying to get their hands on. (Godspeed!)
