Just about every woman wants to be thought of as "sexy" or "alluring" at times. This is especially true if one is interested in attracting a particular someone.
Unfortunately looking sexy may draw attention from people you don’t want to attract. One is only offended if it's the wrong person taking notice. There is no way of saying, “I wore this outfit to attract only him or her.”
Every man and woman has something in their closet which they consider to be sexy, sharp, dashing, or eye catching....etc
It's a bit disingenuous to wear something that "stands out" and act offended when people take notice. If you really wanted to be completely "ignored" you would have worn something that was conservative or drab.
The same thing goes for having several tattoos, body piercings, green or blue hair...etc You have to expect that people will always look at you longer if you stand out from the rest of the pack.
