The change doesn't last past the afternoon, however.; The girls are shopping for bathing suits, and accidently mix up the top and bottom of two bikinis. They decide to buy the bikinis, switch the tops and bottoms, and wear them to the beach, making quite the fashion statement. It doesn't last though when Veronica wants to be unique and stains Betty's top with mustard.; The girls think about their careers after high school: Betty talks about going to an all-girls school, Nancy thinks about a career in chemistry, Ethel wants to attend culinary school so she can nab Jughead, and Veronica wants to go to business school.; Betty models a new outfit for Veronica who's less than impressed.
