Emotional Curses

What about Cassidy, who loses all of her clothing if she gets too excited- in a legitimately cartoony puff of pink smoke?!

Or how about Jessica, who strips herself when she is angry?! And then moves on to stripping her friends?

There's also Karen, who ends up naked when she's embarrassed or ashamed- and yes, the curse continues as long as she stays embarrassed!

Is it one of these girls?
