Sometimes less is more.
Leigh seemingly forgets this lesson and awkwardly embarrasses herself at a charity event in an exclusive sneak peek from tonight's episode!
All the girls are invited to represent Diane von Furstenberg's brand and gracefully mix and mingle with the guests, but some candidates have better luck than others!
"There is one thing I do know how to do well, and that is have good etiquette socially," Cat says. She is definitely at ease making casual conversation, meanwhile Leigh is a little too enthusiastic.
"I thought I was going to have to really keep an eye on Cat, but it turned out, it was Leigh that I needed to be worried about," Style Editor Jessica Joffe says. "I love Leigh so much, but she is totally out of her depth here!"
