    Natural support

    This bra is very comfortable. Snug band fit without biting into me. The fabric is very soft.

    Color is true (Deja blue) in real life. Really vibrant and fun. I have tear drop shaped boobs and this bra’s cup supports me perfectly. It provides very natural support, somewhere between the bliss bralette and base t shirt. I have pierced nipples and they definitely show through, so pasties are necessary (it is unlined after all).

    Personally, I find this bra soft, comfortable, & sexy. I have washed it twice, and seems to be holding up well.

    Comfy/feels like me

    I’m a 36/38 band and DDD or DD cup. I love that this bra is underwater and has some structure but it is that nice soft smooth material so it doesn’t irritate my skin and I can wear it all day and I like how my clothes look over it.

    Current Fave Unlined Bra

    I love an unlined bra that gives you shape and support without any extra padding! Plus, you can convert it to a racerback, so it gives you more flexibility with your wardrobe!
