Kelsey Hall decided to tweet "1,000 retweets and I’ll wear this to all my classes for the rest of the semester."
She ended up with WAY more than 1,000 Retweets!
She wasn't exactly happy about it but, ultimately pulled through and there's plenty of on-campus evidence to prove it.
Kelsey told Buzzfeed that the first day of wearing the tree to class she felt really embarrassed so she enlisted the help of her friends to walk with her.
She even made sure to keep everyone updated.
She also said that walking around campus with an umbrella in the costume was no easy task.
As embarrassed as she was at lease she could hold her head up high, underneath that glowing star.
