Hailey Bieber looked cosy in a Clara Cutout Onesie [1] ($130) by Frankies Bikinis during a stroll in Los Angeles on Tuesday. Shortly after her viral reunion with Selena Gomez [2] — during which she wore a chocolate-brown Saint Laurent dress with a diamond-shaped stomach cutout [3] — Bieber gave the popular fall trend an athleisure twist [4].
While walking toward her car, the model looked ready for a full HIIT workout [5] in the strappy white one-piece, which features shorts and a small stomach cutout just below the bust. From the back, the ruched design reveals a massive back-cutout [6] detail that curves across the lower back, where Bieber had tied a rose-pink sweatshirt around her waist. She styled the look with Raf Simons Cyclon Sneakers [7] ($465) in white, crew socks, a Femme Shoulder Bag [8] ($3,300) by Prada, Balenciaga Oval Sunglasses, and a messy bun.
As leggings and statement scarves [9] take their rightful places in our fall wardrobes, Bieber's everyday ensemble is the ultimate laid-back oufit inspo. The trendy onesie, made of recycled polyester and spandex, is basically the ultimate leisure suit and can be dressed up with a fuzzy trench coat [10], cable-knit knee socks, and ankle boots [11] for a day out, or it can be dressed down with a hoodie and slippers for lounging around the house.
Ahead of her get-together with Gomez, Bieber met up with Kylie Jenner [12] to get into the Halloween [13] spirit. With tricks and treats on the brain, the pair dressed up as Elphaba, the Wicked Witch of the West from "Wicked," in sheer all-black ensembles and matching green body paint to grab pizza.
