Izzy had always been one who prioritized comfort over beauty though she did have some degree of a fashion sense. When she was at home, she didn't dress much differently than Julian did but when she was at school, she was sure to make sure her hair and makeup were done and she was wearing something cute.
After being bullied all through elementary, middle, and high school, she had been determined to turn over a new leaf. It had worked out a lot better than expected because she managed to be surface-level friendly with a variety of classmates and coworkers at both of her jobs.
Her instinct was to spend her precious few minutes between classes reading but she knew that it would be her only chance to talk to people and get on their good sides in case of group projects or needing to have someone to study with for tests. So she endured.
It wasn't always bad. The people she met were nice enough even if they weren't nearly as fun to be around as Julian or Roz.
