Size: 36B Color: Beige

I was Instagram targeted for this style but found this one for almost half the price and I am obsessed with it. So comfy, great neckline, and blends seamlessly with every top. It’s still new so I cannot speak to how it holds up in the wash, but I’ll probably buy another soon.
I’m 5’11” and I wear a 36B. True to size.

Size: 38E Color: White

This bra is so comfortable! There's no padding but the underwater gives plenty of support. I sized up a cup size since I'm bigger busted and it fit perfect.

Size: 34F Color: Beige

It looked nice enough, but as other reviews have stated, it was very squeaky. The metal ring holding the different parts of the strap together squeaked against the fabric no matter what I did to it- I thought that they might have been exaggerating, but the bra was very loud and I didn't wear it long enough to take the tags off.

Size: 36D Color: Black

Listen…I love this bra. It’s perfect. The straps are FULLY adjustable and they don’t fall off my shoulders like every other bra I own. I’ve worn it all day and I’m still comfortable in it. Good lift AND separation. Relatively wide back band with three hooks for closure and 4 sizing spots.

HOWEVER there is one, single, flaw. The circular piece where the back band is connect to the bra strap is made of plastic AND IT SQUEAKS. Loud enough that I can hear it every time I move. 😭

! Help us! Make a version with a metal circular connector!
