437 is my FAVORITE activewear brand. Hands down! Their quality is incredible and the fit is even better. As someone who is super picky about fit, they nailed it.

Customer photo review of The Square Tank / Espresso

I placed a largeeee order on Black Friday. Was nervous since I had never ordered from here but SO glad I did. The fabric is like butter and everything is SO flattering. Flare leggings are squat proof without feeling suffocating. This is my new fave fitness brand hands down. I am 5'5" 145lbs and ordered mediums in the bottoms and large for the tops and onesies. I definitely could have gone with mediums for everything, but it's all good. I don't like for my tops to feel like compression clothing so I'd prefer a more relaxed fit. 10/10 addicted to this brand.

Absolutely LOVE the square tank cut, WE NEED MORE COLORS!!!! :) I'm a 32A cup (shoutout IBTC) and this top makes it look like I have cleavage, never have felt so confident in a sports bra type top!!! I'm a spin instructor and it always stays put when I ride too. If you have a smaller chest I highly recommend this style!!! I'm wearing an XS and it's a perfect fit <3
