SIZING GUIDE

Ultra Boost 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.

STEP-BY-STEP TUTORIAL

How to Use Your Bridal 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.
