Betty's friend Sarah Beth comes to the house to borrow a cocktail dress. Betty suggests an orange dress with white gloves, saying she would look like sherbet. Sarah Beth tells her she can't pull off white gloves after seeing 'Gypsy'. We know they are talking about the stage musical rather than the movie because the movie was released after Marilyn Monroe's death which was prominently featured in this episode.
