    Great Bra

    Tried two other organic cotton bra companies and their bras just didn’t fit well. They didn’t come with clasps and didn’t provide enough cup coverage. This bra fits snug and also provides a little lift. The shoulder straps are thicker than normal but I like that about them. The fabric is soft and the bra is super comfortable. Very happy with my purchase.

    I love this bra!

    I love that this bra is made with organic cotton, especially since I have sensitive skin. Other bras have caused chafing and sweating along the bra line, but this one feels comfortable. I was pleasantly surprised by how well it fits despite the general sizing. The XL gives me just the right amount of lift and shape, and the fabric feels sturdy without being flimsy.
