where is my beret

going to an artist's house soon. leaving in less than half an hour and I do not have an appropriate outfit. for instance, how do I wear a fashion scarf if I also need a real scarf to guard against the elements (which, I note, are currently described as "freezing drizzle")? I do not have any vintage t's - should I just go solid black? or should I wear a real shirt? in that case, how far would an artist unbutton it? and footwear - sneakers? what am I even going for: the working-in-the-studio-with-mild-paint-spattering artist or more of the gallery-opening artist? NOT SURE.
