These handy 3-hook wide bra extenders provide an extra 4 rows of adjustment to most 3-hook bra closures. They are perfect for providing extra room when the bra band is too firm. Ideal for use when you are in between sizes.

Bra extenders are particularly useful to wear with wire-free bras where the cup sizing is very flexible. For brand new bras that have a very firm fit these will provide comfort in the band. Over time when your bra band loosens up, you can tighten the adjustment or remove the extender to get maximum support over the life of your bra. 

B Free Note: This product consists of a single bra extender. The image reflects the front and back view of each extender.

*Sizing Note: Please ensure to select the correct size bra extender that matches the width of the hooks for your B Free bra.

4x5 hook bra extender is suitable for:
