New! Ultra Boost Inserts By: Boomba Size: C Color: Beige The most padded insert on the market. The go-to for that wow factor. Instantly boost up to 2 cup sizes. Recommended for tops with structure in the chest area. Triangular-shaped, best for low v-cut tops Boosts up to 2 cup sizes Double-sided adhesive for extra security Sweat and water-resistant No sewing required and interchangeable between outfits 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 and 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. Never used! I panic bought a couple Boombas not knowing which would fit my wedding dress best. I went with another pair! My loss is your gain! Open to reasonable offers!
