Monica: If you could change your closet with any girl at school who would that be?
Serena: Alexa!!
Monica: Yeah, she has a great style
Monica: But for me it's too much
Monica: I mean she's all about clothes
Monica: And you see her outfits, but you don't see her as a person
Serena: I know what you mean
Serena: But still, she's the best dressed by far
Serena: If I could change clothes, I'd change with her
Serena: And you?
Monica: Maybe with Mia
Serena: I wouldn't have guessed
Serena: She has such a different style. Nothing to do with what you wear
Monica: That's why. I'd like to feel how it is to wear all the girly things 
Serena: I cannot even imagine you in a dress...
If Serena could change clothes with any girl at school she would choose Alexa. Monica would choose Mia. Monica's and Mia's styles are very different.
