Women, when you get dressed up and go out, why does it bug you if guys look at you? (not gawk)

Why is it that you spend all the time and money to look so good, then if a guy gets caught looking even a little, some women look like you just killed her cat? Do you get dressed up so you feel better about yourself and still hope you don’t get looked at? I always thought that was a double edged sword, you want to look beautiful yet cannot help but attract attention. Do you like being looked at? Ate you always looked at everywhere you go?
