PATENT PROTECTED
Demi Boost (Lite) Inserts are abalone-shaped inserts that increase your cup size by one cup. They give your bust a fuller look when you wear those plunging necklines and low-cut dresses.
 |
Prevents nipple slips in low-cut tops |
 |
Interchangeable between outfits, no sewing needed |
 |
Lightweight and super comfy to wear |
Same insert you love, new name! We’ve renamed Perfect Boost Inserts to Demi Boost (Lite) Inserts.
Don’t worry! It’s still the exact same product, shape, and feel you know and love.
Unlike a sticky bra that is supported by adhesive, BOOMBA inserts are supported by the clothing and cannot stay up by themselves. It is crucial to wear them in tight, structured, and fitted tops.
For the perfect fit, we recommend choosing your true size. Only size down if you are in between sizes.
Have augmented breasts? Please check our FAQ section to see if they are suitable for you.
