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.

    Obsessed!!!

    I have tried SOOOO many sticky bras and have hated all of them! I saw ads for these inserts and finally caved. I bought the Ultra Boost and Demi Boost. I wasn’t sure if they were going to work on me because I have very small boobs but these worked wonders! All of my low cut tops fit so much better now and the double sided stick is amazing. Do not walk, RUN to buy these!!!

    AMAZING!!!

    So i bought these to wear with my wedding dress. I went for my first fitting and i was so wowed and amazed how great these worked!! Easy to apply. Customer service is on point you tell them your bra size and they will tell you the cup size to buy which was a plus for me. Definitely purchase you won’t regret it.

    Love the diversity!

    Just bought my first pair of Boombas and am super excited to try it. Have not yet received it, but I just wanted to applaud the amount of shades and sizes that are offered. You don't often see sticky bras with these many shades and I am here for it.

    May need a new pair soon..

    I love these inserts and they are my holy grail. I originally bought it in December for my wedding in August and ended up wearing it all the time under my outfits that they probably won't last till my wedding lol. For others that are wondering, I bought these to my fitting and it made my dress feel so secure and really gave me a more balanced silhouette which I appreciated. This is really the perfect wedding bra I have been looking for since all the other ones on the market had clasps in the middle and would probably fall off if I started sweating.
