Sisters Bra

$28 $78

Color: Terra Firma

Inspired by the engineering of suspension bridges, the Sisters Bra is designed for maximum security, support, and coverage at all points. The name alludes to the sisterhood in its design: two layers of construction working in harmony. An inner layer, which includes unique meshes and molded cups, while attaching those elements to an inner set of straps. This inner layer = encapsulation, supporting each breast. The outer layer and outer straps represent the compression, holding everything in place. The four-strap system more evenly distributes the weight, relieving strap pressure which can often cause pain or welting in the skin. The Sisters Bra is also higher on the neck, to minimize top bounce, with the two layers of mesh at the neck serving both form and function.

Can’t have enough of these!

I have five different colors of this and can never get enough. Will always be my go to!

Great idea…not executed well

The bra is a beautiful color. And the straps are super supportive. The fit isn’t correct. I ordered my size 38 DD and it’s extremely tight…I needed help putting it on. In addition the extra mesh layer is unnecessary and hot. I’ll still wear it because it’s final sale but this could’ve been better executed.

All time favorite

This is my all time favorite bra(aside from the beloved Brooks Juno bra that has been long discontinued). I have this bra in all the colors. They are so supportive and I like that the front of the bar is double layered. It doubles as extra storage when I don’t have enough pockets. Please keep making this one!

Sisters Bra

If my sisters lived with me, I would be able to secure the strap in the back with some help. Even if I was married, I could wear this bra. The point is, that I need help getting the bra on.
