SIZING GUIDE

Ultra Boost Inserts

Should your bra size be a mystery, take a bust measurement and contact us using those figures.

At 34F and above, our Demi Boost Inserts (double push-up) run as far as 34I, while our Invisible Lift Inserts (lightly padded) reach all the way to 34M.

Bear in mind the result shifts with bust size and shape, landing somewhere close to a double push up bra. BOOMBA’s padded inserts perform best on natural breasts.

Tip: go with your actual size for the closest fit. Drop a size only when you fall between two.

Need guidance on sizing or which insert style suits? Don't hesitate to contact us for more help — we would genuinely love to hear from you!

Hate it when your sticky bra edges into view above your neckline? So do we!

BOOMBA®’s Demi Sticky Bra has a shape all its own. We cut the cups on the Demi Sticky Bra lower so the bra never shows above your top. Those cups mould to your own curves for cleavage that looks natural, and the stitch-free edges keep everything smooth and seamless under clothing.

Built to vanish beneath a low neckline
Fastens with a clasp to deepen cleavage
Light to wear and breathes well
Made for backless styles
Easy to wear from dawn to dusk
Wash it and use it again

Go with your actual size for the closest fit. Move up a size only when you fall between two.

We would not suggest our products for anyone with thin or reactive skin.

Do note our inserts are not meant for anyone with thin or sensitive skin, nor for women who are pregnant or nursing.

A WALKTHROUGH, STEP BY STEP

How to Use Your Bridal Inserts

1 Wear insert
Set them into the garment first, then press that onto the breast.
3 SECURE
Press insert and garment together against the breast to lock it.

A WALKTHROUGH, STEP BY STEP

How to Wear Your
Sticky Bras Correctly?

1

Make sure you are wearing proper garments. 

The strongest results come from heavy, close-cut (non-
stretchy) garments, ideally structured through the bust.

2

Get the garment on first.

3

Place the inserts onto the clothing. We DO NOT recommend
pressing the insert onto bare skin at the start, which brings
lopsidedness and puts a good result further out of reach.

4

Scoop breasts up to the desired position. Scooping is the
step that matters most, because it leaves the bust
settled on the inserts at an angle that reads naturally.

5

Press insert and garment against the breast to lock it.

ULTRA BOOST INSERTS

The most natural-looking boost I have come across

I used to tuck my bra straps down into the cups, but I never felt secure — they shifted about and I kept expecting a strap to pop back out. These inserts solve it completely, giving the most natural-looking boost I've come across. If they're still on your list, treat this as your nudge. Easily the best thing I've bought!
