For those who love their curves bold and beautifully defined, our Extreme Morticia Underbust Corset takes vintage shaping to the next level. Cut to the same elegant pattern as our bestselling Morticia, this curvy underbust corset is tailored for a more dramatic silhouette — designed for those with a 12” difference between waist and mid-hip.

HORIZONTAL MORTICIA CORSET MEASUREMENTS

The rib and hip are measured approx 5" up and down from the waist.

VERTICAL MORTICIA CORSET MEASUREMENTS

It is important to check the length of your torso to ensure that the bottom of your corset doesn’t dig into your thighs or breasts when sitting.

With a waistline two inches smaller than the standard Morticia, it’s ideal for the naturally very curvy or for experienced wearers looking to size down. The result is an extreme underbust corset that delivers an unmistakably hourglass figure while maintaining the comfort and craftsmanship What Katie Did corsets are known for.

Inside, the structure is everything you’d expect from a serious corset: a spring steel busk, spiral and flat steel bones for balanced support, and an internal cotton waist tape to maintain strength through wear and training. The outer layer of matte satin (100% polyester bonded to 100% cotton) feels smooth and luxurious, while the baby pink 100% cotton lining adds a soft, vintage touch.

Whether worn for daily waist training or reserved for special occasions, the Extreme Morticia offers the perfect fusion of structure, elegance, and drama. Ethically crafted in Thailand, it’s proof that extreme curves can be achieved with grace and comfort.

Optional modesty panel available separately. Specialist dry clean only.
