Kino. Kino. Kino.
Start off with light tapping on the shoulder. Then wrap your arm around her. Light touching at first, then get more firm (it comes with the courage). Then when your faces are getting closer, kiss her.
If you have a prolonged kissing, you can even try feeling her.
^^This, kino is really the only thing that matters, the more shes into it the more you'll feel comfortable with it. Ones that give me a good green light are doing things like putting your hands on her hips or a finger in her front pocket. generally I'll do the fingers in the pockets when we are standing face to face, I'll pull her closer by her pockets, or walking up behind her, your hands on her hips and looking over her shoulder is also very natural.
When you kino enough...trust me the kiss will happen.
