Make your profile pic different and interesting
Your profile pic is your face to most people. It’s the first thing people notice when you invite them and it says a lot about you. Like they say a picture is worth 1000 words. So make it stand out somehow. Make it attractive but not too sexy that you’ll get into trouble.
And pictures of you with another girl don’t make you more attractive to anyone except possibly the person in the picture with you. I’m not sure if guys think that it will make a girl think they are more attractive because at least one girl likes you, but it can have the opposite effect. I have accepted random invites just because the picture was interesting and I figured it was worth checking out.
