Tip: For the perfect fit, we recommend choosing your true size. Only size down if you are in between sizes.
For sizes 34G and up, our Invisible Lift Inserts (lightly padded) are available in sizes up to 34M.

For Demi Boost, size Extra-Small will be shipped for sizes AA, size Small will be shipped for A, B, C, size Medium will be shipped for sizes D and E, and size Large will be shipped for sizes F and G.

Please note that results may vary depending on breast size and shape. Results will be similar to a double push up bra. BOOMBA padded inserts work best with natural breasts.   


If you need any help with sizing or insert styles, please feel free to contact us for further assistance, we'd love to hear from you!
