Gravity Brassier

The gravity brasier is a scale bodice that was originally worn by Madame Murel. But she was quickly dispatched before she could use it. Soon after it was aquired by Mobster Kingpin who used it to become Dark Matter Mobster Kingpin (won't let me link). Unlike normal bodices instead of modifying height and vim, and  are modified. So far this has only been used to increase mass for defensive purposes.

Interesting Fact:

If the gravity brassier has any similarities to other bodices then DMMK's legs are sticking out somewhere in the universe.
