437 is a contemporary swimwear and athleisure brand known for its fashion-forward approach to minimalist, curve-flattering designs. Founded by Toronto natives Hyla Nayeri and Adrien Bettio, the label first gained recognition for its signature bikinis—celebrated for their seamless construction, versatile fits, and subtle sexiness. Today, the brand’s offerings include swimwear, activewear, and matching separates such as leggings, sports bras, shorts, and lounge-ready essentials, all designed to accentuate and support a range of body types. 437 is favored by a style-conscious audience seeking elevated basics that transition from poolside to post-workout, combining comfort with a confident, feminine aesthetic across its core categories.

437 is all about elevated essentials—think luxe swimwear and buttery-soft athleisure that hugs in all the right places. Effortless cool meets comfort-driven design.
Usually true to size, but keep in mind: their signature sculpting fabric loves curves. In between sizes? Size up for that lived-in, lounge-all-day vibe.
Absolutely. 437’s silhouettes double as sleek bodysuits or sporty crop tops—just layer on relaxed denim or flowy pants, and you’re off-duty perfection.
Sustainability is on their radar—think small-batch drops and mindful production. Chic with a clear conscience, but keep an eye out as they evolve their eco-story.
437 is designed in Toronto, and most of their dreamy swim and apparel is produced right in Los Angeles. Canadian vision, laid-back California finish.
