I was 100% influenced to try 437 after seeing Shelby Sapp wearing their bras in one of her reels... and I am SO glad I did.
I originally ordered two bras and the moment they arrived I ABSOLUTELY loved it. The quality is honestly unlike anything I've experienced from other activewear brands.
For reference, I usually buy from Lululemon and Alo, and I've also tried CSB (which was ok), but 437 is on a completely different level. The fabric is incredibly soft, supportive, flattering, and just feels luxurious. The fit is amazing, and somehow they're comfortable enough to wear all day while still looking so good.
I loved my first order so much that I immediately went back and bought four more bras.
437 has officially become my new favorite. If you're on the fence, this is your sign! It's absolutely worth every penny!!!
