Im very direct when I do day game. No point beating around the bush. Make sure she knows youre chatting her up. It will come across as ultra confidence (which is all good!) if you go indirect, you'll come across as shifty... You don't want her to think you're trying to rob her!!

"hi, was just walking by and I saw you from over there... I just had to stop you and say you look really nice."

Then explain what it is you like about her; style, the way she walks, her confident dimenor, etc and get her to talk about herself.

Then go from there to start off with.
