What shoes for job interview?

I will be wearing a black pencil skirt, cream cami with lace detail, black fitted suit jacket with small cream pinstripe. The interview is for a sales management position. I live in South Carolina so it is full swing summer here. Is an open toed shoe ok? Do I still wear pantyhose if I do wear an open toed shoe? Should I stick with a black shoe? I am feeling like it is too much black and maybe I should go with silver or something like that to make it a little more special. Would another color work better? I will be interviewing with a man if that makes a difference. Please help. I have never had a job that required professional business attire and I want to make a good first impression.
