SIZING GUIDE

Demi Boost Inserts

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

At 34M and above, our Invisible Lift Inserts (lightly padded) reach all the way to 34R.

For the Demi Boost, size Extra-Small will be shipped for size AA. Size Small will be shipped for sizes A, B, and C. Size Medium will be shipped for sizes D and E. Size Large will be shipped for sizes F and G. Size Extra-Large will be shipped for sizes H, I, and J, and size 2Extra-Large will be shipped for sizes K, L, and M.

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

A sticky bra supports itself through adhesive; BOOMBA inserts do not. It is the clothing that holds them, which makes tight, structured, fitted tops essential.

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

Breast implants? Our FAQ covers whether these will suit you.

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

FAQs

What is the way to apply BOOMBA Inserts?

Groundwork counts! Skin should be clean and dry before BOOMBA inserts go anywhere near it. Leave off makeup, oil, lotion and other products — they all undermine the adhesive.

Put the garment on first. Slide the inserts inside it without letting them touch skin, then scoop the breast into place and press insert and fabric together against it.

What sets BOOMBA inserts apart?

Conventional padding sits loose; BOOMBA inserts grip on both faces, bonding to the garment and to the skin at the same time for a firmer hold. That keeps them out of sight and guards against slips.

No stitching is needed to hold BOOMBA inserts steady! Press them onto your skin and onto the fabric! Moving them between different tops and dresses takes seconds.

How many reuses do BOOMBA Inserts have?

With sensible care BOOMBA inserts will see you through 40+ wears. Give them a gentle clean after each outing and put the protective films straight back on — that stops dust, lint and stray particles settling on the adhesive and keeps them performing.
