Outfit ideas for Angela Webber at Barnes and Noble

I'm going to a Breaking Dawn release party at BN and I had been planning on going as Bella for the longest time. About an hour ago I changed my mind and decided to go as Angela. Does anyone have any ideas on a very general idea of what i should wear and how I should do my hair and stuff to look like her. Please note that I can't go out and buy anything, I don't have time. Thanks!
