Revamp Ultra Boost (Lite) Inserts Sizing Guide
Ultra Boost (Lite) Inserts
If you are unsure of your bra size, please measure your bust and contact us with the measurements.
For sizes 34F and up, our Demi Boost Inserts (double push-up) are available in sizes up to 34I and our Invisible Lift Inserts (lightly padded) are available in sizes up to 34M.
Please note that results may vary depending on breast size and shape. Results will be similar to a double push up bra. BOOMBA's padded inserts work best with natural breasts.
