I wanted to make the point that she's not necessarily an untrendy dresser, but she dresses to blend in, and is very buttoned-up. She majors in a male-dominated department (mathematics) and although there are other women in the dept. who dress more femininely, Emily chooses not to. She always pulls back her hair, even though it's very curly and sticks out. She dresses like she's going to a mathematics competition, which is her default "uniform". The school's insignia is on the front pocket of her blouse. Because she's very practical, she wears a belt with her khaki slacks and comfortable flats constantly.
