Putting this out quickly before a tie starts again lol

Okay, it seems Hellfire is going to win. These are my top 3 for the record:

1. Season 4 blue

2. Season 2 sweater

3. Season 4 Hellfire

The only reason Hellfire is so low for me personally is because multiple characters wear the shirt so it's not really a unique, original outfit...but it does look really good on him, I agree

Edit: Some more of my favorites

4. S2 Black jacket

5. S2 Ghostbusters

6. S4 Plaid

7. S2 Snowball
