How to use BUST UP inserts

Please note that our inserts are not intended for individuals who have sensitive or thin skin or women who are pregnant or breastfeeding.

Like traditional inserts, BUST UP inserts need to be used inside clothing. They cannot be used by themselves.

STEP 1

  • Wear the garment on your body. Tighten the garment if possible for best results.

STEP 2

  • Stick the inserts onto the inside of your clothing item and not to your skin.

STEP 3

  • Scoop breasts up and towards the centre to create cleavage.

STEP 4

  • While scooping, press the insert onto the breasts and press firmly to secure.

STEP 5

  • Make sure both sides are even in the mirror, adjust if needed.

Sizing

If you are unsure of your bra size, please measure your bust and contact us with the measurements.

 

For sizes 34F and up, our Demi Boost Inserts (double push-up) are available in sizes up to 34I 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.
