Pre-orders will be shipped out by Feb 7.



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
  • Sweat & water resistant 
  • 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.


Have augmented breasts? Please check our FAQ section to see if they are suitable for you. 


The sizing guide below only serves as a guideline. For the most accurate fit, please measure your garment and contact us.

Please note that results may vary depending on breast size and shape. Results will be similar to a double push-up bra. BOOMBA results work best with natural breasts. 

Demi Boost Inserts:

Tip: always size down if you're in between sizes for a seamless fit.

Please note, Demi Boosts come in three sizes (small, medium, and large). Size small is suitable for cup sizes AA / A / B / C, size medium is suitable for sizes D / E, and size large is suitable for sizes F / G.


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. 



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

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

Scoop breasts up and towards the centre to create cleavage.
While scooping, press the insert onto the breasts and press firmly to secure.
Make sure both sides are even in the mirror, adjust if needed.

Great product and great customer service

Had a hard time finding a good bra to stay hidden under my wedding dress and these definitely did the trick! They really gave the girls a good boost and lift and felt secure throughout the day. Also just wanted to shout out the amazing customer service, you guys were patient and really helpful with your recommendations! Thank you Jessica!

Works great~

This product works great! I have bought other sticky bras before and I was not happy with them. They always fall off when it gets hot and they do nothing to make my boobs bigger, only pulls them together. These really made me look like I naturally had bigger boobs. This is now my go to brand for any sticky bras! So happy they created these inserts! I love them!

Don't doubt the magic!

These inserts are fantastic! I was pretty skeptical at first because I have bought lots of crap on ig in the past that did nothing for me, but I was sold after seeing my favourite YouTuber review it. They do exactly what they say they will! This will definitely not be my last purchase!

I am a 34A and have never had cleavage in my life, I really wanted to have cleavage in my wedding dress and was worried I wouldn’t be able to find anything to make it happen. I tried tape, normal “sticky boobs”, etc. A week before my wedding I discovered Boomba and knew I had to try it! I was worried they wouldn’t come in time even with rush shipping, so I emailed customer service and they assured me they would get them to me in time for my wedding and they did! Amazing customer service!! Sure enough they gave me amazing cleavage for the first time in my life and I felt so beautiful and feminine in my wedding dress!! They were so easy to use, and stayed in place the whole day and night, AND I never had to worry about a nip slip! THANK YOU BOOMBA!!!

really works!

It's such a simple product but it works so well! It really helps me balance out my wider hips, giving me more of a hourglass appearance. I really love this insert, cannot wait till the weather warms up to use them in my bikinis!
