Flexi Bra Underwires

A pair (2 pieces) of bra underwires in a classic balconette style. Our wires are strong & lightweight & this particular style has extra flex for added comfort.

To find your match, lay your old underwire on top of our free printable underwire chart to compare its shape and size. (Make sure to print at 100% scale so the sizes remain accurate!)

Please note: We've updated the way we label our Flexi Wires. What used to be called sizes 30–36 are now listed in European sizing as 65–90. For example:

• Size 30 is now 65

• Size 32 is now 75

• Size 34 is now 85

• Size 36 is now 90

This change helps us offer an extended size range, now running from 65 up to 125. If you’ve bought these before, just match your old size to the new number using the guide above.

Ideal for bra making or as replacement underwires for an existing bra.

If sewing your own bra, please check the size of wire you require by measuring the cradle or cup edge on your pattern. You should allow 1-2cm for wire play.
