About the brand

437 is a Canadian lifestyle brand founded in 2017 by best friends Hyla Nayeri and Adrien Bettio while studying business at Queen's University. Named after their Kingston address at 437 Johnson Street, the brand began as a swimwear line created to offer universally flattering styles that empower women to feel confident in their bodies. Originally frustrated by the lack of flattering bikinis while studying abroad in Europe, the duo invested $1,000 each to launch their vision. What started as swimwear has evolved into a successful activewear and apparel brand, with activewear now serving as the primary revenue driver. Known for its minimalist aesthetic and flattering cuts that hug women's curves, 437 has become the uniform of clean-girl Instagram culture, worn by celebrities like Kylie Jenner, Kendall Jenner, and Jennifer Lopez. The Toronto-based, all-women team remains self-funded and was featured on Forbes 30 Under 30 in 2020.

love that they're giving they definitely went through everything that females go through and we kind of nitpick. so I love that they take a really good time and effort like you can see how much effort they put into their pieces.

Obsessed is an understatement. These are the most flattering workout shorts! I get endless compliments whenever I wear them. They snatch your waist in and make the booty pop. Need one in every color and every length!

these leggings are super nice and thick and they just feel high quality i love that there's no front seam i don't have any like at leisure type leggings with the no front seam. but then there is still that nice V seam. in the back to shape the glutes.

One aspect where 437 Swimwear excels is in the quality and durability of their products. Many customers report that their swimsuits maintain their shape and color even after multiple uses and washes. This longevity is an important factor in sustainability, as it reduces the need for frequent replacements and minimizes waste.

While 437 has gained popularity on social media, it has received mixed reviews from customers... Customers have reported issues with the fabric quality; it's essential to try on the pieces before purchasing to ensure comfort and fit.

While 437 Swimwear has made some efforts towards sustainability, it would be an overstatement to classify the brand as fully sustainable at this point. The company's use of conventional materials and lack of comprehensive sustainability reporting suggest that there is still significant room for improvement.

I really wanted to like it given the branding around it, but the fabric is so not it. For the price the fabric is not buttery, not soft and not stretchy at all. I'm pretty sure I broke a couple of seams getting the leggings up because the waist line was designed to be smaller than the bust, but for athleisure wear there shouldn't be any restricting seams

the material is super super soft it's very velvety smooth i can tell that this is super high quality one con though that I already do notice is that this material looks like it's going to peel because as y'all can see up close it has a little bit more fibers that kind of stick up.

the new isabelle swimsuit line is all so so basic, the most basic colors and cuts, but they're selling a one piece for over $100? they usually make high quality unique pieces, but lately a lot of stuff has seemed incredibly basic.
