    Beautiful bra

    First time ordering from negative underwear and very happy with my purchase. I’m small chested and have trouble finding bras that make me feel beautiful as well as feel comfortable showing off. This one hugs in all the right areas, no extra fabric or weird gap.

    Great bra

    This bra seems like it will be great. The underband was just a little big on me. Unfortunately, there are no white ones in stock in a small size at this time. Really hoping they are back in stock soon so I can really try it.

    Just OK

    I love the color pattern and it’s very comfortable but it is not very flattering when actually wearing a shirt as kind of makes my breasts separate and flop outwards which I don’t really like. I don’t think I’ll return it but I was a little disappointed because it is so cute!
