Cimorelli

Cimorelli is a singing group from El Dorado Hills, California that first gained popularity on YouTube singing cover music. They were subsequently signed to Universal Music's Island label. Now composing and writing their own songs, Cimorelli is made up of six sisters: Christina, Katherine, Lisa, Amy, Lauren, and Dani. Their music is mostly made up of a cappella singing with occasional instruments.

Where are the Cimorelli sisters when they become naked and how does it happen?

Also, do all six sisters experience unexpected nudity at the same time? Or is it just one of them? Or is it some combination of them less than all of them?
