1 - Looks like St. Patrick's Day threw up.
2 - Holy ****. Looks like someone just learned how to use Photoshop. If my toddler fingerpainted this, I would ball it up and throw it in the trash.
3 - Very clean, professional.
4 - Reminds me of the big game unis, white top, orange pants. But it has a 90s Starter jacket feel.
I think 3 is the best choice here to represent the school.
