Perfect Boost Inserts

32 reviews



Perfect Boost Inserts are abalone-shaped inserts that increase your cup size by one cup. They give your bust a fuller look when you wear those plunging necklines and low-cut dresses.  

  • Prevents nipple slips in low-cut tops
  • 100% sweatproof and waterproof
  • Interchangeable between outfits, no sewing needed
  • Lightweight and super comfy to wear

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.

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 Perfect Boost Inserts come in one size that fits A to D cup. 

Perfect Boost Inserts:

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


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. 


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.

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.

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.
