    This is my new favorite bra. It's so soft, excellently supportive, and is snug enough in the band to stay in place regardless of how I move. The color looks super cute as well.

    Favorite bra

    As someone who is petite and yet has a larger bust I have STRUGGLED to find a bra that is supportive, gives me a natural shape and actually fits me properly. Harper Wilde is the first bra that I honestly can say has fit me so well! I recommended them to all my girl friends because I couldn’t say enough good things!

    Love this bra! I have a narrow back and boobs that wrap around to the sides, and its (typically) impossible to get a good fit. This bra has it all - structure, comfort, and good views from the outside

    I forgot my bra...oh wait, no i didnt!

    Silky smooth and feels like youre wearing nothing at all yet getting the support u need. Nothing pinching/digging in and love the time to replace timeline on the band! It did run a tad big in the band size
