I am 6'3" and a half, and I often wear 3 to 4 inch heels. When I going dancing, which I do often, I am usually the tallest person on the floor of either sex. I just expect that I am going to get noticed, and also expect that along with attention, people will figure out my DNA makeup. If somebody close by, stares at me, I just smile at them, and say "Yes I am', and then turn away. I know that my philosophy runs opposite to many here, but I am not terribly worried about being clocked. I certainly would not make any style choices simply to reduce my visibility and exposure.
