BOOMBA Fit Guide

BOOMBA Sizing Chart

BOOMBA inserts are suitable for various body shapes and sizes. However, you need to determine your bra size to make sure you get the best fit for your body. 

While Demi Boost and Invisible Lift comes in two sizes, small size to fit A to C cups and the medium size to fit D to E cups, Ultra Boost, on the other hand, comes in various cup sizes.

Check out our size guide to find out which one is suitable for your body. Please note that results may vary depending on breast size and shape. Results will be similar to a double push-up bra and work best with natural breasts.

How to Measure Your Bra Size

In measuring your bra size you need to determine your band size and your bust size. That way you will know your cup size.

How To Wear BOOMBA Inserts? 

For some users, it does take a few tries to get it in the right position (just like getting your sticky bra to stop being lopsided), so we recommend checking out our tutorial blog for a better idea of how to use the inserts. We recommend putting the inserts on in front of a mirror to ensure it is even on both sides. You can adjust the level of cleavage according to your own preference. Just remember to scoop and stick, to ensure your cleavage stays put throughout the day! 

If you'd like, our team can also record custom videos for you or get on a video call with you to help you with the use of the inserts.
