Guillotine Ballgown

This slimming garment is fastened with laces, buckles, and buttons and reinforced with ribs of leather or bone along with razor sharp guillotine-like blades near the base. A Guillotine Ballgown grants a +4 armor bonus to AC. If the wearer is a witch, each day when she communes with her familiar to prepare spells, she may enhance one hex she knows, increasing its caster level by +2 for 24 hours. This enhancement ends if the corset is removed or if she uses it to enhance a different hex. As apart of your move action, while you wear the gown, you begin spinning and continue to do so until the start of your next turn. Until then, each creature that you move within 5 feet of, or that moves within 5 feet of you, must make a DC 10+ your dexterity mod saving throw, taking 3d6 slashing damage on a failed save or half as much damage on a success. A creature can take this damage only once per turn. Attacks of opportunity made by creatures within 5 feet of you have a -10 while you are spinning.
