I've recently been seeing girls wearing petticoats over their pants like little tutus.   

Seriously, how is this okay? Here's how a petticoat is meant to be worn:

Under the skirt! It's a slip that poofs up your skirt--not a tutu.

This one's so voluminous! :]

What do you think about wearing a petticoat over your pants? Would you do it? Have you ever seen it?
