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.

didn't think I would like them this much

I didn't expect to like this product as much as I did. Originally I thought it was a silly product and purchased without high expectations. But they really surpassed all my expectations in terms of customer service, quality, packaging and functionality. 1) I have a top that always slides and shows my sticky bras, even with double-sided tape. These inserts were able to hold it in place and keep the top from moving. 2) The shape actually looks so natural. I was worried that with so much padding, it would look very fake and obvious. I wore it out to dinner with my girlfriends and everyone commented on how good my girls looked. A lot of them were shocked when I revealed it was boomba and turns out 2 of them already have these too lol. 3) The stickiness is superior to all sticky bras I have tried in the past. I have used them so many times and they are still sticking strong. 4) I am a sweaty gal and they did not move at all since I guess my top keeps the inserts in place, which was nice as I finally do not need to worry about my sticky bra falling to the ground. I did not feel any movement or shifting throughout my day. 4) packaging is absolutely beautiful, customer service is attentive and actually cares (shoutout to Jessica for helping me find my size!), these inserts are seriously not like any other sticky product I have used before. From thinking I would use it every now and then, I feel myself grabbing them everytime the occasion fits because they just make your outfit THAT MUCH BETTER. Overall I am very happy with my entire experience with Boomba and would recommend them if you are looking for a good sticky bra

Good quality adhesive

I have been using these for months and they still stick on very well! The adhesive feels really nice and does not leave an oily residue like the cheaper sticky bras I have tried from Target do. These work great for when I wanna wear my backless tops and dresses!

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!!

I feel amazing with my Boombas!

I am thrilled with my Boombas. I just bought the Demi Boost because I’ve been on the fence about a breast augmentation and wanted to try them out. I wear them inside my normal bras and I feel fuller and sexier. I don’t think I’ll need the surgery for awhile since I’m so happy with the results. Very excited to wear them with my swim suit. I highly recommend if you’re looking for a new look without surgery!

Buy it

These silicone sticky pads work pretty well. They add a little oomph to the breast but not all crazy like the videos show. Best to wear these with very tight sculpted tops that have under wiring to get best results in the lift and so they dont move around.
