Watch out Sandy! Here comes the  Cha Cha DiGregorio from the rival gang The Scorpions in this Adult Grease Cha Cha DiGregorio Costume.
This dress was famously worn by Cha Cha when she won the dance off with Danny.
This officially licensed costume includes a knee length black halterneck dress with turquoise tulle petticoat underneath. The dress features a flower design all over and the bust is made of turquoise ruffled tulle. The finishing touch to this costume is a matching tulle hairclip.
