Plunge Bra Underwires

A pair (2 pieces) of bra underwires in a plunge style. These wires are strong but lightweight and fairly flexible offering comfort and support.

Ideal for bra making or as replacement underwires for an existing bra. These MS09 underwires are a good match for most M&S (Marks & Spencer) plunge 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.

Please note that the exact thickness of wire may vary from size to size due to Love & Lace sourcing from new, EU based suppliers, however the size and shape remains consistent and matches that on the free printable PDF which you can download here.
