Tip: For the perfect fit, we recommend choosing your true size. Only size down if you are in between sizes.


For sizes 34F and up, our Demi Boost Inserts (double push-up) are available in sizes up to 34G and our Invisible Lift Inserts (lightly padded) are available in sizes up to 34M. 

Please note that results may vary depending on breast size and shape. Results will be similar to a double push up bra. BOOMBA’s 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!
