I know everyone says be yourself -- we also know it doesn't always work. Any tips : What kind of clothes do guys like, hairstyles? I'm so sick of being invisible, I have tons of guy friends, and no prospective boyfriends!
fall flat on your face and a guy will notice you, and then he asks if you're alright, you say, "yeah I'm ok, *give a little laugh* my name is ---, how are you?" and you guys strike up a conversation...it sounds like something out of a movie, but seriously, if you do that in front of a cute guy who doesn't seem like he's in a rush to get some place, I can almost guarantee he'll say something =P but you have to be cute about it, don't start like cursing or anything, don't try to make a huge scene by shrieking or anything...if he's worth giving a damn about he'll take the time to ask if you're ok.
I guess just following the trends, finding outfits that look cute or fixing your hair a bit. I usually look at vogue or elle or some magazine that is about fashion. I also have a lot of guy friends and sometimes they're really helpful in terms of telling you what guys want.
