    A great daily bra

    I wear this with all my sweaters or other tops where I don't need the coverage of the t-shirt bra. So comfortable!

    These bras are really fantastic. Great coverage, no squeeze out and the strap adjusters in the front are so helpful

    IN LOVE with the Base Unlined Bras!

    Perfectly supportive even without the padding for my 38B chest. So soft and comfortable. I absolutely love wearing them. My go-to daily bra now. Can't wait to keep adding to my collection!
