PATENT PROTECTED
This padded insert is specially designed for demi cup styles. Stick it inside wedding dresses, bras, bandeau bikinis, etc. for a natural-looking boost.
 | Natural-looking boost designed for demi cup style clothing |
 | Boosts up to 2 cup sizes |
 | Prevents nipple slips in low cut tops |
 | Insert stays put and keeps clothing in place |
 | Interchangeable between outfits, no sewing required |
 | Our inserts are not intended for individuals who have sensitive or thin skin or women who are pregnant or breastfeeding |
Unlike a sticky bra that is supported by the adhesive, BOOMBA inserts are supported by the clothing, they cannot stay up by themselves. It is crucial to wear them in tight, structured, and fitted tops.
For the perfect fit, we recommend choosing your true size. Only size down if you are in between sizes.
Have augmented breasts? Please check our FAQ section to see if they are suitable for you.
HOW TO USE BOOMBA INSERTS
Please note that our inserts are not intended for individuals who have sensitive or thin skin or women who are pregnant or breastfeeding.
