outfit for dinner at his place ?

hey guys! I’ve been talking to a guy from my university for a few weeks now, he just turned 22 and i’ll be 21 in a few weeks.

he invited me over to his place where he’s going to be cooking dinner for us. normally i would think this calls for a pretty casual outfit, but it’s our first date so i’m not sure if i should dress it up a bit?

we’re in jersey so it’s cold here (only 30* today), but does anyone have any suggestions on what kind of outfit to wear ?
