70-m540 Long line underbust corsetThis long line underbust corset is cut to sit just under the bra line, coming low over the stomach and hips. This has been our most popular corset in our London boutique for larger waist sizes, as it gives a flat tummy and a smooth hip outline under clothing. Corsets are sized according to your waist size, not dress size. Corsets should be ordered 2 4 inches (5 10cm) smaller than the natural waist size. e. g. a 26" waist should order a 22" corset.
