Bust Ups Bra Inserts turn your favourite bra into the ultimate breast enhancer, adding noticeable volume, shape and lift without changing your bra. Designed to sit naturally within the cup, these padded bra inserts enhance your bust while maintaining a smooth, discreet finish.

Contoured to follow the breast’s natural fall, Bust-Ups feature a full coverage soft-shell design that increases breast volume by more than one full cup size. The super soft padding provides extra oomph while sitting comfortably inside your bra, helping improve cleavage and shape instantly.

    How Our Secret Weapons Work

    Frequently Asked Questions

    check_box

    How do I place bra inserts correctly so they look natural and stay in place?

    Slide each insert into the cup of your bra at the bottom or side, depending on the shape you want. Adjust them until both sides feel even and comfortable.

    If your bra has pockets, place the inserts inside for extra stability.

    check_box

    Can bra inserts help increase my cup size or add more cleavage?

    Yes. Bra inserts can create a fuller shape, add volume, and enhance cleavage by lifting the bust or filling out the cup.

    Choose inserts that match your bra size and the look you want, whether it is a subtle boost or a more noticeable lift.

    check_box

    How do I stop bra inserts from moving during the day?

    Ensure your bra fits well and sits firmly around the ribcage. Place the inserts deep into the cup and smooth them flat.

    Bras with pockets or firmer fabric hold inserts more securely and prevent shifting.

    check_box

    How do I clean and care for bra inserts?

    Bra inserts can be hand-washed with warm water and mild soap. Allow them to air dry completely before putting them back in your bra.

    check_box

    Will bra inserts work with any bra style?

    Bra inserts work best with bras that have structured cups or pockets. They may shift in unlined styles, so always test placement before wearing them out.
