How To Wear BOOMBA Sticky Inserts?

For some users, it does take a few tries to get it in the right position (just like getting your sticky bra to stop being lopsided), so we recommend checking out our quick tutorials for a better idea of how to use the inserts. We recommend putting the inserts on in front of a mirror to ensure it is even on both sides. You can adjust the level of cleavage according to your own preference. Just remember to scoop and stick, to ensure your cleavage stays put throughout the day!

What To Wear With BOOMBA Sticky Inserts

BOOMBA inserts need to be supported by the clothing they're used with. They work best with structured, thick, and tight (non stretchy) clothing. Since they are inserts, they need to be held up by the clothing itself. If your top is stretchy and not tight, the top will not be able to push up against the inserts to hold your cleavage in place.
