Character's Party Outfit Analysis

Brittany's party outfit consists of a black dress, black tights and heels. She is wearing some red lipstick and red accessories which connotes that there is hidden danger and she is not to be trusted.
Her outfit is short and she is wearing heels to suggest that she is quite a party girl and is dressing to impress. This can imply that she is more worried about social status than grades or friends.

Jinx's party outfit is made up of just a plain, simple white dress. This suggests that Jinx is very straight forward and what you see is what you get. She is innocent and very naive.

Jinx is almost the complete opposite of Brittany as she cares about her friends as well as how she does in school. We can see this as Jinx is shocked when Brittany doesn't turn up as she is not used to going to parties or being ditched by friends.
