There is always Monopoly
The woman with the Monopoly money dress appears to have a strange relationship with the game. It’s probably not out of line to assume she has the board hidden away – maybe it’s a mid-prom game? Whether or not that is the case, this character has an odd connection with the board game, even wearing a necklace like her Monopoly money gown.
It’s possible that it’s a kind of demonstration for everyone else: she wants to be making a lot of money in the future. It might, however, simply be another method for making a statement.
