Rokko can't propose Rita until he has a tailcoat.

Did you talk to Rokko. He said the architect knows where to find these.

He is in the future zone. Talk to him.

Yeah, go figure. Maybe you should tell him about the latest hat fashions.

Except the missing piece? Get yourself the latest Hats magazine and read the magazine (look it in the inventory). Now you can tell the real latest hat trend.

Right. Say that to the architect. He gives you the portal map to find the tailcoat.

There was someone in the diner ready to help you.

Right! Show the map to Vince, at the diner. He will take you there.
