So today I was at the mall, and while buying a new shirt, I looked up and saw a HB9. She walked by me and asked if I needed a fitting room. I held eyecontact, smiled, and said yeah please. After I finished in the dressing room, I went to pay and again, got the eye contact and smile from her, and I smiled back and held her eye contact. Her friend was asking her if she liked this bikini she was looking at, and I looked at her friend, chuckled a bit, gave her a wtf is that!? look, and she looked at me and laughed. They both seemed to like me. I still haven't really said a word to either of them other than the usual customer/worker talk, but they both seemed to be looking at me and smiling a lot.

After I paid, I thanked her and left.

So basically, my questions are

Do I still have a shot with this girl?(I would think so since all of the signs I got from her were IOI's)

What is a good way to attract and close her? I can't really use them as a 2 set, becuase her friend obviously won't be there all the time. (She was working with another girl, so I could possubly use them as a 2 set) I was thinking picking out 2 shirts, asking her which one she'd reccomend, then going with the other one. After that I'm pretty much out of idea's. I've never tried opening a girl that was by herself, in the day time, while she's at work, so I'm not entirely sure what's going to work here and what I should avoid. I'm guessing for the most part I'll just have to start with the opener and just play it by ear from there. Any tips would be awesome.
