How to standout to guys?

Genuinely I’m never seen guy guys true story I’ve walking around in ballgown before never got even a glance. I’m an introvert but for my entire life people have never really acknowledged me and at this point in just lonely. When I walk around my neighborhood they’re are a ton of kids my age but somehow when I’m out I never see anyone. I don't even have any rumors or anything about me people forget I’m there most of the time. I dress my best everyday (cute outfit, hair done, makeup done, still nothing) What can I do?

About the ballgown thing since someone else used that as a reason why people wouldn’t like me: The ballgown was for Halloween. No one else gave any effort (ie barely anyone dressed) and I lost to a girl in a everyday outfit (jeans tee shirt) who had a price of paper on that had princess peach written on it. I wore a 50s pink gown I’d thrifted, a blond wig, and a crown. I felt like complete shit.
