be in formal dress code...
you should be dressed and on your way already...
so you're really just going to ask your neighbor if you can cut their lawn?
take a shovel
nice. not tux nice, but dress pants and a nice shirt nice. maybe a tie if you have a nice one. you are going to an interview and you should always dress nice for that
you should dress very smart
nice/casual, I mean.. don't wear a suit but at least put on a nice button up or something... clean jeans?
