To wear pantyhose or no?

I would wear either off black pantyhose with your dress or sheer black tights. They will make your legs look much better, and I wouldn't worry about your legs not being perfect because not many girls have perfect legs either! That's what pantyhose are for, they will smooth out any imperfections and you will look very sophisicated in it! Be sure to get the right size (usually a size larger) and there are some with natural maging fibers which will keep you feeling good all day.
