Act confident. Even the most gorgeous woman has insecurities. Try to see what other people see, in the best light possible. Ignore minor issues and realize that it’s probably that you’re the only one who notices those tiny things. Compare yourself to others if necessary, noting your positive points.
Look happy. Wearing a scowl, whether you’re really angry or just not smiling, is not going to attract men. Make an effort to project an easy, kind smile. If you must, look directly at a guy and smile at him, but don’t overdo it. You don’t have to be too toothy; just a simple, nice smile will do, as if you were admiring something you like.
Make eye contact. A man won't likely approach a girl when he thinks he doesn’t have even a glimmer of a chance. If you catch him checking you out, meet his gaze and hold it for a few seconds. This will let him know you’re interested.
Pay attention to your body language. In order to project that you’re open and approachable, keep your arms at your sides instead of crossed in front of you. Lean forward instead of backward if someone is talking to you, and strand straight up instead of slouching and looking unhappy.
Stray from the pack. There’s nothing wrong with going out with a ton of your girlfriends, but remember that most men aren't going to brave your friends to get to you for an introduction. It would be just as intimidating if you were to walk into a group of eight handsome men, hoping the one you had your eye on was interested. Linger alone for a bit -- walk slowly to the restroom, browse the jukebox or order your own drink from the bartender.
Avoid being overly flirtatious. You can seem happy and fun without letting every man in the area know that you’re available and ready to mingle. Flirting with everyone within arm’s reach will make the cute guy nearby look for a girl who’s less busy.
