Tell her the truth. I've found that telling a girl that they have a unique characteristic about them that stands out(EX beautiful eyes or a stunning smile) always works best. If you just tell them that they are beautiful it sometimes does not mean as much to alot of women just because it seems like something you would say to anyone. Generally, a girl will have at least one thing that just blows you away. It always means alot to them when they hear that you noticed it.
Walk up to her, smile, sincerely tell her - without stuttering - that you think she's beautiful and that seeing her makes your day much nicer, smile again and walk away. Do not look back and do not wait for a response. If she wants to say thank you she'll catch up with you or call your name or something. The big thing is to leave it at that and get away immediately; you don't want to look like you're waiting for a response, that totally spoils it. If it's like you don't care what her response is, that's so much cooler. . Be prepared to hear her say you're a freak as soon as you turn your back, but don't worry about it. Most girls will act weird around other girls but having someone say you're beautiful is usually nice, someplace deep inside. Whatever you do don't expect a good response right then - what you're doing, it's like a gift - you can't expect anything in return. Don't do it more than once to her - do not make it a daily thing - and don't ever do it to more than one girl because girls talk to each other and the other girl will be pissed off that you said the same thing to some other chick. If she says it freaked her out and not to do it again, nod, say ok, and never do it again. That's the thing that's hardest, and the thing that's most important.
Tell her shes beautiful , and shes the most amazing girl you met
kiss her and tell her shes beautiful. look into her eyes and tell her you love her
look her in the eyes and tell her shes hot
Tell her what she really means to you. Tell her shes beautiful. Tell her your not fake. Tell her shes the best thing that's ever happend to you.
Give her a mirror and hold it up to her and tell her EVERYTHING is perfect about her. Another good line is tell her shes gorgeous. HOPE THIS HELPS!
Tell her these things as long as theyre true: Shes pretty shes nice shes generous shes popular shes smart she has nice hair she has beautiful eyes
Tell her that shes already beautiful and that she doesnt need to change anything about herself.
tell her shes beautiful. then tell her that every time she smiles and laughs it puts a smile on your face to her happy. also tell her that you like everything about her, her smile, her laugh, when shes angry, when shes sad, when shes hard working, and when she crys. and tell her things she doesn't notice about herself. girls dont reallly notice things about themselves (trust me, im a girl). then tell her you love her.
Tell her, "I think you are the most beautiful girl in the world."
