Go to the scene right before Jerry and Renee's first date. Renee needs to change her shirt, so she goes in her room with her sister. She takes off her shirt and is in her bra, holding up the shirt that she wants to wear and looking at it. The camera cuts to her sister saying a few words which takes two seconds, then it cuts back to Renee and her shirt is perfectly on and her hair is all strait and perfect. It's pretty easy to see.
