Being a girl, i find the best way to do it is to take her somewhere private (sometimes boys say your beautiful but are so caught up in their friends that it looks like you don't mean it). Run your fingers though her hair. Most of all, compliment her on why you think she is beautiful, she might even ask you what you like about her. Also, make sure she is the one, because if you say it but then break up with her and get a new girlfriend then she could think that you call everyone beautiful.
Tell her, "I think you are the most beautiful girl in the world."
I think you are beautiful. Just say it.
Damn! You are a sexy!
No, you should never tell a girl her friend looks more beautiful than she does it will make her sad.
Tell her eyes are beautiful.
You cant freak a girl out by telling her she is beautiful because girls loved to be told their beautiful because it makes their self-esteem better but if you cant tell in her in person just write a note saying i think you are beautiful,(:
"Beautiful Ending" by Barlow Girl. Great song!
unique,tell her that she is different from other girls
kiss her and tell her shes beautiful. look into her eyes and tell her you love her
Just be honest with her. And tell her she's beautiful.
Tell her shes beautiful , and shes the most amazing girl you met
You tell her:''you are beautiful'', ''your eyes are beautiful'' and you should buy her some chocolates.It works!
