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.


Like traditional inserts, BOOMBA 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.

    Wedding Day Hero!!

    I purchased a wedding gown that had a low back and a deep cut in the front, so wearing a bra was absolutely not an option. My bra size is 34 DDD or E, and I was concerned about pulling off this dress. The person at the dress shop told me it would be fine with the straps tightened. Fast forward to 2 months before my wedding, we could not tighten the dress, as it would be super uncomfortable for me to wear, and my boobs were falling out under the built in cups. I was absolutely panicked, every other silicon insert I have tried DOES NOT WORK. Then I stumbled upon Boomba, the DOUBLE SIDED STICKY BRA INSERT! They were absolutely perfect in my dress. I stuck them on the cups inside my gown and they held me up all day long. I put them on at 2pm, and still had to peel them off at 11:30, as the were really on there still. My boobs looked great. I felt so confident and was able to dance all night long too! I have already told all of my girlfriends about this company. Thank you Boomba for this product!!

    AAAAAA-MAZING!!! I was a bit dubious this would work as usual lifting products have not had the desired effect! However these are honestly incredible! I’ve shown my friends who are also getting them now! As the difference is so good!
