Flat metal Bra underwires with painted color coded tips. The sizes given are suggested bust and cup sizes. Underwire size will vary according to the garment it is to be used in, it is best to select your underwire by both the length of the wire as well as the size. You may want to try adjacent sizes to determine the correct one for your sewing project. Hint: If you can’t get your exact length, get a longer size, cut them off at the tips and cover the ends with epoxy glue. This will keep them from poking through the fabric.
