My OCs, Vic and his boss (at that time), Aaron.

Aaron talked Vic into wearing formal clothes to work on Mondays. At first, Aaron wanted Vic to wear shirt and tie every day, but since Vic was also being trained by the army, he sometimes wore activewear. So Aaron said for all the office days, wear shirt. Vic objected and compromised for ONE day. Aaron sealed the deal, making it Mondays.

Vic would rather wear fatigues than shirts.
