It's very hard to find cotton bras, actually almost impossible. Natural fibres are very important to me. Not only is it a beautiful breathable cotton fabric, its thick elastic band is comfy and doesn't dig in, the ladies don't fall out when bending over which is rare in a v cut, I'm 30 weeks pregnant and I finally have some nice bras that will also be perfect for breastfeeding. Love love love! Will be buying more soon
