Not a Sweater—Hailey Bieber's Favorite Pre-Fall Wardrobe Basic Makes Leggings Look the Coolest

If there's one fashion girl to keep an eye on for comfort-meets-style outfit inspiration, it's Hailey Bieber. Whether she's grabbing coffee, taking a Pilates class, or tackling mom duties, her style consistently proves that you can prioritize comfort without sacrificing elegance. This past week, Bieber showcased yet another effortless look, demonstrating how a "dated" staple can make black leggings or pants feel fresh for 2026.

For a casual dinner in L.A., Bieber was spotted wearing sporty black low-rise pants paired with a white T-shirt. She layered the look not with a sweater, half-zip technical jacket, or even a pullover sweatshirt, but with a black zip-up hoodie. She then finished the ensemble with her go-to retro sunglasses and a black leather tote bag.

If you've been following Bieber's recent off-duty style, you'll know that this isn't her first time embracing the zip-up trend. Just days earlier, she was seen wearing a black sports bra and leggings with the same sweatshirt, followed by a look featuring pink shorts and a gray zip-up. The pattern is clear: the versatile hoodie has become one of Bieber's go-to layering pieces. It works for every part of her busy life and is a functional piece for chilly summer mornings and the summer-to-fall transition.
