Our new bustle wire is a flat steel boning, covered with a thin coating of plastic. It is narrower than our previous boning at 5mm (1/4"), but is thicker than standard boning. It is lighter weight than our previous boning, and has a very similar spring and firmness to our old boning.
Please see the chart below for sizing options.
**Note: For very heavy dresses, I recommend doubling up on the boning for extra support. Either place 2 sets of boning in side-by-chanels, or together in the same chanel.
