Bra Underwires

A pair (2 pieces) of bra underwires. These classic style wires are slightly longer than my balcony wires. They are strong but lightweight and fairly flexible offering comfort and support.

Ideal for bra making or as replacement underwires for an existing bra. These MS03 underwires are a good match for many M&S (Marks & Spencer) bras. 

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!)

If you are making 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.
