In S1E18, Madeline and Louise are discussing Tristan’s usual “type.” Louise says, “Tristan usually likes his girls bad.” Madeline tells Paris, “Looks like we’re going to have to do a Pink Ladies makeover on you.” Louise adds, “Turn you from a sweet Sandy into a slutty Sandy dancing at the school fair in high heels, black spandex, and permed hair.”
“Grease” is a musical that opened on Broadway in 1972. It was made into a movie in 1978 starring John Travolta and Olivia Newton-John. The story follows two groups of high school students in 1959: the T-Birds and the Pink Ladies. Both groups consider themselves rebels, but Sandy, a new student, is accepted into the Pink Ladies despite being a “good girl.” In the end, Sandy ends up getting a makeover to impress Danny Zuko, a member of the T-Birds. She ditches her skirts and sweaters in favor of black leather and spandex and shows up at the school fair singing “You’re the One that I Want.” Danny actually earned himself a letterman’s jacket to impress Sandy, too, but he quickly takes it off when Sandy shows up.
