I should have this figured out by now

Tuesday we are having our engagement pictures. We should have already taken care of this by now but we have no idea what we are going to wear. I have seen hundreds of engagement pictures and some people dress up, some people dress down and some do both with multiple wardrobe changes. I am now worried about picking out one outfit and wondering if two outfits is really necessary. The point of the pictures is to get some shots of us in regular clothes so that we have some nice pictures other than those of us on our wedding day. I am just wondering is it really worth all the fuss?
