      I'm embarking on a new fitness journey, and I've realized that having a stylish workout set really motivates me. This prompted me to go on a big shopping spree to find the cutest workout sets out there. With fall approaching (and celebrities everywhere reintroducing flared leggings and outfits suitable for errands), I’ve compiled a list of eight of the trendiest activewear brands. So, if you're looking to wear leggings in fall 2025, consider these brands. Discover the best workout sets, flared leggings, and activewear brands favored by celebrities and fashion influencers below.

      Kendall Jenner showcased the khaki Adanola Ultimate Leggings on Instagram last month, and they've quickly become a favorite among fashion insiders for their fall-ready look. Deep khaki isn’t the only color gaining popularity this season; celebrities are also embracing shades like beige, chocolate brown, and heather gray. Take a cue from Kendall and grab a pair of these best-selling leggings to enjoy the buttery-soft fabric.
