Jack watches the donning of clothes with a distinctly disappointed look, since what he's seen so far is rather nice, but okay, early twenty-first century, so fair enough. He supposes he ought to put some clothes on too. He glances through the clothes in the cupboards and drawers, and eventually puts on out a light blue shirt and a pair of dark trousers.
He grins at Ianto as he pulls out the waistcoat he occasionally wears for a change from the braces, and slips it on, buttoning it easily. "Jack Hahkner, nice to meet you too! Coffee would be great,thanks."
