I'm kinda unconfortable to make this question cause i don't think that i look like anyone that i'm gonna talk about but i need an opinion.
It happened this year 4 times that a person told me that i look like someone..and every time i was very unconfotable cause i find those girls really pretty and i can not accept that I'm like one of them
Anyway they told me first that i look like Audrey Hepburn, then like emily ratajkowski, then alessandra mastronardi and at least micha burton
but i can not understand how they are saying something like this cause i find them very different
so do you guys think that those 4 girls have something in common? and what?
