SIZING GUIDE

Demi Boost (Lite) Inserts

If you are unsure of your bra size, please measure your bust and contact us with the measurements.

For sizes 34F and up, our Demi Boost Inserts (double push-up) are available in sizes up to 34I and our Invisible Lift Inserts (lightly padded) are available in sizes up to 34M.

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

Tip: For the perfect fit, we recommend choosing your true size. Only size down if you are in between sizes.

PATENT PROTECTED

Demi Boost (Lite) 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
Interchangeable between outfits, no sewing needed
Lightweight and super comfy to wear

 

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.

Here’s Why It Stands Out

What Makes Our Demi Boost (Lite) Inserts Different?

Boost Up to 1 Cup Size

For everyday wear. Padded to lift and boost 1 cup size in sweetheart necklines.

Double-Sided Adhesive

Built-in adhesive keeps inserts secure and in place, so you can move freely with confidence.

Sweat & Water Resistant

Designed to withstand heat, sweat, and splashes—perfect for long wear, day or night.

No Sewing, Fully Versatile

Easily interchangeable between outfits; best worn with structured, fitted tops for maximum lift and hold.

Why Choose
BOOMBA?

BOOMBA products are created by women for women. That’s why our products fit better and feel better, because we have also experienced the same struggles you have right now.

We create our products using the best materials and really put care and thought behind the design to ensure a seamless and comfortable fit. When you wear BOOMBA’s products, you will definitely feel and see the difference.

STEP-BY-STEP TUTORIAL

How to Use Your BOOMBA Inserts

1 Wear insert
Place the inserts onto the clothing, then stick it onto your breast.
2 Scoop Up
Scoop and ensure that your breasts are resting on the inserts in a position that looks natural.
3 SECURE
Stick the insert and clothing onto your 
breast to secure the position.

STEP-BY-STEP TUTORIAL

How to Wear Your
Sticky Bras Correctly?

1

Make sure you are wearing proper garments. 

For best results, it is important to wear thick, tight (non-
stretchy) clothing, preferably with structure in the bust.

2

Put on your article of clothing.

3

Place the inserts onto the clothing. We DO NOT recommend
sticking the insert onto the breast first, as it would cause
unevenness and make it harder to achieve desirable results.

4

Scoop breasts up to the desired position. Scooping is the
most important step, as it ensures that your breasts are
resting on the inserts in a position that looks natural.

5

Stick insert and clothing onto your breast to secure position.

DEMI BOOST (LITE) INSERTS

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!

DEMI BOOST (LITE) INSERTS

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.

DEMI BOOST (LITE) INSERTS

MUST GET !!!

Seriously these might be the most comfortable sticky bra type thing I own. It keeps my nipples from showing and gives your boobs a pretty shape. It feels like you’re literally wearing nothing. No straps falling off, no metal clasps and I can literally wear as deep of a v-cut as I want and not worry about parts of the bra poking out under. I love that I can wear these inserts with tops I cannot even wear sticky bras with.

Demi Boost (Lite)

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.
