This padded insert from BOOMBA is specially designed for demi cup styles. Stick it inside wedding dresses, bras, bandeau bikinis, etc., for a natural-looking boost. 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. Have augmented breasts? Please check our FAQ section to see if they are suitable for you.
