I like my wife to dress how she is comfortable. She don't have to impress me, she already did, and that's why I married her. I love her for who she is, not how she dresses. But she looks good, when she has to.
I read a study once that said that the sexiest amount of skin for a woman to show was 40%. Google it for a better explanation. they did a study on men who rated pics of thousands of women and the ones that were consistently chosen were the ones that bared a little less than half their skin. Some examples would be a long-sleeves minidress with heels, jeans and a tank top, or cowboy boots, miniskirt and T-shirt. I think it sounds legit.
