PATENT PROTECTED

The most padded insert on the market. The go-to for that wow factor. Instantly boost up to 2 cup sizes. Recommended for tops with structure in the chest area.

Triangular-shaped, best for low v-cut tops
Boosts up to 2 cup sizes
Double-sided adhesive for extra security
Sweat and water-resistant
No sewing required and interchangeable between outfits
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 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.

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.

From Our Lovely Brides!

  • Ordered them to use under my wedding dress and overall this insert served its purpose.It made my breasts look more perky and was comfortable to wear.

    Kate C.

    Verfied

  • Exactly what I was looking for my wedding dress! Looks super natural and actually makes a huge difference in my boob size. I would highly recommend other brides.

    Nikki M.

    Verfied

  • I don't normally write reviews but this product really deserves it. I wore it on my wedding day to help boost the girls a bit in my wedding dress. Not only did these inserts give me amazing cleavage, it also really stuck on well and I mean WELL. It did not move throughout the day at all and it was VERY hot and normally all sticky bras will fall off the moment I step out into the heat. They stayed stuck and I did not even have to worry about bending over in my plunging dress, it kept my dress really stuck to my skin. This is honestly one of the best products I have tried all year. Definitely recommend them to all brides!

    Claudia

    Verfied

  • I wore these on my wedding day for over 8 hours, I forgot I even had them on. I loved knowing they were secure, so I did not have to worry about them moving or falling out. I definitely recommend these for all brides-to-be!

    Emma

    Verfied

  • These inserts were the perfect solution for my chiffon bridal dress! Because of the low plunge and almost sheer material, sticky bras would have shown in the middle. These inserts were perfect for more coverage and to avoid any wardrobe malfunctions. They didn't budge at all all day, even when I sweated a little!

    Agnes A.

    Verfied

  • I just received my BOOMBA's and I am BEYOND impressed! I have a wedding coming up and have a huge gapping issue due to the design of the dress. The inserts WORKED PERFECTLY to help me fill out the gap and made my boobies look so nice, and I loved that it didn't move or show at all at all even when I moved my arms and bent over. I am so happy with the results and I already loved my dress before, but now I love it even more since it fits my chest area so much better! Can't wait to use my BOOMBA's on my wedding day!!
