Photo: Real Simple / Michelle Barnes Matching sets have been the go-to outfit for people who want their clothes to be stylish yet comfortable for so long, they’re practically inescapable on social media. And one brand that’s become hugely popular among TikTokers and Instagramers alike is Set Active. Set Active’s goal is to provide activewear that looks polished enough to be worn from the gym straight out to brunch. All the styles are intended to be worn as monochromatic, matching sets to make picking an outfit so much easier. Set Active is known for limited-time drops, but it just launched a permanent lounge collection for the first time. The Core Collection includes wide-leg sweats, jogger pants, sports bras, tanks, zip-ups, and more that are comfy and fashionable. Not only are the items designed to be worn together, but they’re available in four neutral colors—Oxford (navy), Blanc (white), Espresso (brown), and Onyx (black)—that can be mixed and matched with other clothes, too. The best part is that all the lounge pieces are made of Set Active’s waffle knit fabric that stretches as you wear it to give it a lived-in feel.
