Super soft, a little loose, but it is so comfortable. I am a size 2XL, and I’m so grateful that this company has sizes for plus size women. Love this!

Nice bra

The keyhole bra is very comfortable and I like the hole for air circulation. It's very soft and I love that they have adjustable straps So many organic bras do not have them. This color is pretty.

So comfortable! Especially for us plus size curvy ladies. I wear 3XL and the band and cups are a tiny bit loose, but its so comfortable. Its so hard to find something organic that is plus size and comfy, but I am super happy and will be repurchasing!
