This bra feels like a hug!

I absolutely love this bra! After kids and nursing I had pretty much given up on finding a comfortable and flattering bra. Most underwire bras make me feel claustrophobic, but not this one! It gives me such a great, natural, shape, its completely smooth under shirts, doesn't give me any underarm or back bulge, it's comfortable to wear all day and even to sleep in. I love that there is no padding and the design is minimal, but sexy. I am ordering more and replacing all of my old bras with these.

Love this!

Really love this bra. It is super high quality, soft materials, but is still supportive. I wear a 34DDD and it's always a craps shoot on fit, especially with a non-molded cup, but this fit perfectly
