Unlike in the general fashion world, activewear trends don’t tend to change very quickly. Most people stick with the basics—think a black workout set, white tube socks, and white sneakers—because they work. They don’t show sweat, are easy to clean, and look put-together post-class or gym session. That being said, a new fitness look is trending right now, and it’s quickly becoming just as trusted as the aforementioned trio. I’m talking about all-black leggings, sneakers, and socks, skipping white accents altogether to create a sleek, monochromatic ensemble that’s just as versatile, but feels fresh and modern in 2026.

One reason why this all-black leggings outfit is so popular at the moment is because of Dakota Johnson, who was recently spotted arriving at a workout in Los Angeles wearing it, specifically choosing Lululemon leggings, black Nike V2K sneakers, and Adidas black socks. She finished off the look with a hot pink crop top, a black New York Knicks cap, and Khaite x Oliver Peoples cat-eye sunglasses. It was a no-frills, effortless combination, and yet, the pairing of her all-black leggings, socks, and sneakers made it feel intentional and chic.
