Mona Lisa Smile Ladies as Pink Ladies

Watching this movie for the first time, and I couldn't help comparing these girls to the Pink Ladies
  1. Betty = Rizzo
    rough around the edges, complicated
  2. Joan = Frenchie
    comforting friend, fun
  3. Giselle = Marty
    loves older men, flirtatious
  4. Connie = Jan
    sweet, misfit
