Suit with briefcase and a hat.
Choices of gray, brown or yellow suit. But i think Yellow suit is the best fit for the story because later on in the story Mark has to go to a hotel called Banana Hotel. Yellow suit pairs it with blue tie and black shirt or brown shirt is also fine too.
Change to yellow tie!
But if I can’t get a Yellow then a nice and classic brown, gray or blue suit are fine too and pairs the suit with yellow or blue tie.
