Most Helpful Guy
Anything that accent's a girl's figure and shows off her curves makes for nice eye candy. But just because it's nice to look at doesn't make it attractive, per se. Many men use a girl's wardrobe to try to figure out aspects of her personality before actually approaching her. Usually guys who are interested in pursuing something long term rather than something fun or casual are like this. And to guys who try to use your wardrobe to analyze you, those same types of clothes and outfits that make for "eye candy" will also be a turnoff.
Think about it this way: A girl dressed in clothes that are meant to look "sexy" is like a sleek jungle cat on the prowl. It's beautiful to behold, but at the same time, you want to maintain a safe distance because you just KNOW there's a whole world of trouble waiting for you if you get too close.
What this also means, and girls should note this, is that just because a guy is checking you out doesn't mean he likes you or has any intention of approaching you. It's very likely he just likes the view and wants to leave it at that.
