BOOMBA Fit Guide

How to Know You’re Buying the Right Bra Insert for Your Size

How Are BOOMBA inserts Different?

Unlike traditional inserts, BOOMBA'S patented inserts are sticky on both sides, which means it sticks to your clothing and to your skin for extra security. It prevents nipple slips and stays hidden under clothing. Another great benefit of the double-sided adhesive is that there is no sewing required. Simply stick the inserts onto your clothes.

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.

Demi Boost and Invisible Lift comes in two sizes, Small and Medium while Perfect Boost comes in one size fits all A to D. In comparison, Ultra Boost comes in one size with different 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 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 quick tutorials 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’re still unsure if your outfit can be used with our inserts, please don’t hesitate to send us an email or a DM and we’d be happy to help!

What To Wear With BOOMBA Inserts

BOOMBA inserts need to be supported by the clothing they're used with. They work best with structured, thick, and tight (non stretchy) clothing. Since they are inserts, they need to be held up by the clothing itself. If your top is stretchy and not tight, the top will not be able to push up against the inserts to hold your cleavage in place.

In this article you will determine what to wear with BOOMBA Inserts, click here.

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.
