It does seem to be a mistake that a lot of people make. This is more common in people that have low self esteem already, regardless of how pretty they are. Media doesn't help alleviate the issue - between woman's magazines that seem to focus on "looking better" and "getting the guy" and entertainment where most woman are gorgeous and possible only serve as a romantic interest, there does seem to be pressure on women but it's always seemed to me very distant and not worth worrying about in "real life".
Personally, looking good to appeal to the opposite sex has never been high on my agenda - even as a teen. I was totally vague in high school. I'm fairly certain that I wasn't cool but I didn't get bullied and I had good friends - so I was very lucky in that regard. Basically I want to look good in a "not a total mess in track pants and a 10 day old shirt way", I want the person I fancy to think that I'm attractive (it would be a weird relationship otherwise) and I do like being complemented on appearance (amongst other things), but there's plenty of things that I value higher and strive to improve far more than how I look. I've definitely had worries about myself (we were all teenagers once), but once again they've focused on aspects that I value higher than beauty.
