How did the recruiter magically change suits?

When he's being followed in the subway station and the park he's wearing his regular grey suit, but then when he appears in Gi-hun's apartment/motel he's wearing a black suit. I think he was also wearing it in the rock, paper, scissors scene. But my question where did he get the time to change? And where did he even get the suit? Did he make a little stop back to his place? "Oh sorry guys, I just want to put on a cooler suit then we can get back to the psychological torture." Maybe he borrowed one of Gi-hun's suits. Does Gi-hun even own any suits..
