Same insert you love, new name! We’ve renamed Perfect Boost Inserts to Demi Boost (Lite) Inserts.

Don’t worry! It’s still the exact same product, shape, and feel you know and love.

Unlike a sticky bra that is supported by adhesive, BOOMBA® inserts are supported by the clothing and 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.

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

FAQs

How do I use BOOMBA Inserts?

Preparation is key! Before using BOOMBA inserts, make sure your skin is clean and dry. Avoid applying makeup, oils, lotions, or other body products, as these can affect the adhesive’s ability to stick properly.

Start by putting on your clothing item. Then, place the inserts inside the garment without touching the skin. Finally, scoop your breasts to your desired position and stick the insert along with your top onto your breast to secure.

How are BOOMBA inserts different?

Unlike traditional inserts, BOOMBA inserts are sticky on both sides, which means it sticks to your clothing and to your skin for extra security. Preventing nipple slips and easily staying hidden under clothing.

BOOMBA inserts require no sewing to stay in place! Just stick to your skin and to your top! They are easily interchangeable between different tops and dresses.

How many times can I use BOOMBA Inserts?

BOOMBA inserts are designed to be reusable for up to 40+ wears with proper care. To extend their lifespan, gently clean the inserts after each use and reapply the protective films right away. This helps prevent dust, lint, and other particles from sticking to the adhesive surface and ensures long-lasting performance.

Worth every cent

I was the maid of honour for my best friends wedding. I saw these inserts at the bridal store where she got her dress and I was impressed with the results on her.

I got a pair as well but didn’t know how to use them. I have never used anything that was sticky on both sides before on my chest. I found this brand on Instagram and sent them a DM, they replied instantly with really helpful videos. I was able to achieve the results I was looking for on my best friends big day.

Almost perfect

Overall, they really work so well with my House of CB dresses and give a nice natural-looking fullness, but they are definitely NOT sweatproof if that is what you are looking for. I was at a wedding where all of us were in direct sunlight, so it was getting real sweaty to say the least, and I noticed the inserts were no longer sticking. After they dry, they work like usual but also haven't got a clue how to dry them quicker than air drying. I was a dummy and tried to use paper towels to dry them quicker and now it's permanently stuck on one of them so don't do that lol. I was going to wear these for my wedding, but the lack of being sweatproof has me worried and I ruined one of them. Not even sure if it's possible to make them sweatproof, but I figured it was worth mentioning for anyone who gets really sweaty. Lastly, make sure you follow the size guide. I am a 38B and trusted the guide to get the D cup and it works perfectly. But overall I totally recommend them. Much better than a bra.

I can feel the difference

As soon as I tried this sticky insert one on, I could feel the difference compared to my cheaper amazon sticky bras. The sticky part feels less yucky? I am not sure how to describe it, but it doesn't leave a gross residue on your skin and its a lot stickier, but it doesn't hurt to remove at all. I have used my pair over 5 times now and they are still very sticky, whereas my amazon ones can only be used a max of 3-4 times before its disgusting and the adhesive is peeling off and not sticky anymore.

The shape of the insert is also really nice, it looks very natural under my dress and I got a lot of compliments the day I wore it out to my friends engagement party. Everyone wanted to know my secret since I was clearly not wearing a bra under my backless dress but my girls were sitting real perky lol.

The packaging was very nice, I am a sucker for nice packaging! The shipping was also quite fast, I got express shipping and it arrived within 3 days.

If you are on the fence, get these! They really do just add a little extra something to your outfits and really give the girls a nice perk and nice shape! I am in love with these babies and reach for them quite often now.

Stayed in place

Was really natural in my bikinis and stayed put while I was jet skiing and did not feel like it would slip out at all during the whole day. No one could tell I was wearing inserts, but my bestie did ask if I was on my period lol because my boobs suddenly got much plumper and perkier.

MUST GET !!!

I purchased the bunk ! These was amazing! Worked with any tight top I wore . I bought them to wear on the holidays and now I use it daily :) . It gives you the right amount of volume without it being to extreme. Looks soooo natural ! Just try them for yourself.

Excellent customer service

My review is way overdue since I purchased these about a month ago, but I just wanted to say Boomba has some wonderful customer service and take their customers' needs and concerns very seriously. I purchased these for a specific top, which was very thin and lacked structure, and was really disappointed when I opened the box and saw the instructions that said that these are not suited for the top I had. I was also very upset because nowhere on the product purchase page did it mention that, and returns are not accepted. But after sharing my concerns, Boomba took them seriously and immediately updated the webpage to fix the mistake - which I wasn't expecting at all, because many companies nowadays will just ignore or block people who criticize them. I was also swiftly compensated (with the condition of proof that the item is destroyed and not actually being worn by me). Anyway, I just wanted to share this because I'm happy to see a company that takes criticism and their clients' trust seriously, which so many companies don't. I'm sure the quality of the product is also great, but be sure to wear them with a top that isn't super thin like mine was, or the inserts will be visible. (if you can see the outline of a bra underneath your top, I think you will probably be able to see these too.)

They made my girls look amazing!!

I wore the boombas with a low cut white dress that I wore to an all white wedding, and I got compliments 👀the whole time! It was 90 degrees during the outdoor ceremony and did not cool off much during the outdoor dancing but the boombas stayed in place , did not budge and I danced a lot!! Easy to wash and are still sticky.

Nice for swimsuits

Added volume to my 34B cups. It’s nice for swimsuits, I used them in the pool yesterday and they felt secure.

Cannot feel them at all

These are great! As described. You don't feel them, no sweating and they don't move at all because of the stickiness. I would recommend to my friends if they are looking for something like this!

Too under rated

These are too under rated! I have the ultras and perfects and these are really good for a small boost. The ultras really make your girls stand out but if you are looking for something more chill, these are a good option!

M
Monique
Looks very natural! Love it

I like this one a lot! I have the ultras and the lift ones and this one is very natural but you can definitely tell a difference. I think this is more of a brunch with the girls type of insert, and the padded ones are like out for a date type of insert. I really like both but think you guys should expand the sizes more as I noticed perfect boost only has 4 sizes compared to the others.

100% Worth to buy ❤️❤️❤️❤️❤️

I’ve always been a fan of the sticky bras which I bought online but these BOOMBA products are game changer! They’re magical and have different sizes like the actual bra you wear everyday. It has double sided adhesive that will last long and won't irritate your skin, washable and reusable up to 40x and YOU CAN see the instant volume in seconds and it gives me that BOOM CONFIDENCE, and I won't forget how I LOVE THE AESTHETIC PACKAGING!!! Will definitely recommend this brand to my friends.

demi vs perfect

I purchased the demi boost in the past and loved it, so I came back for the ultras. I saw there was a brafix bundle so I went for that one instead this time to see the difference between the perfect boosts and demi as they look quite similar in shape. The perfect boost are pretty much same thing but smaller and less padding. The difference isn't as dramatic as demi, I would describe perfect boosts as a normal push up bra and the demi as a bombshell bra. I personally like both depending on what I am wearing since I have found use for both. I tend to use the demis for a more sexy curvy look for a night out and the perfect boosts for more like girls brunch type of thing, since it's more day time appropriate for me. Oh take care of the plastic cover it comes in or get extra films T.T! I have no idea how I keep losing them so I stick them on my plastic bags to keep them from getting dirty but actually it made them really gross, so I do NOT recommend doing that.

Better than the original padding

I have used these in bras and bikinis. They are ideal for replacing the original pads.

Best confidence boost!

I wanted something to give me a little boost for my bikini when we went on our trip, and let me say these did not disappoint!! I felt so secure and even being in water I didn’t feel like they were going to fall out! Definitely will be buying more when these ones wear out!

love love love

bought these for my 1 piece bathing suit since the padded insets it came with were pretty much flat and I was hoping for a little lift since I’m a small B cup. These definitely did the trick and made me look like a D cup.
