You already are beautiful in someone's eyes no matter what anyone says.
Look beautiful by believing you are <3 ;)
By enhancing your natural features with soft makeup, shiny hair, and a great attitude. :)
Well you need to be confident. I know everyone says that, but if you feel confident it really shows and brings out the best in you. A big thing that can change how you look is your hair. Finding a good hair cut for you can make ya look really nice. Also, wearing natural make up (foundation, earthy eyeshadows) and maybe a little liner, mascara, and lip gloss can look nice
