Getting a girl to notice you is the same in every situation: a bar, work, school, whatever! It's a huge game of some poker; lots of bluffing, exaggeration or downplaying depending on what the subject is. In essence, it's a game. Don't feel bad for thinking about it this way. Now, some people have been able to slightly hit the nail on the head with advise (take it slow, be friendly, firlt a little first = good ideas) some are just way too off to let me stand idle (just asking her = friend zone with hot girls). But luckily, I'm here to give you some A1 advise that'll help you get through this. (whihc is advise that ANY good relationship counselor/book would give you).
There's a reason good pick-up artists are called "smooth operators". That's because they get woemn attracted to them without the woman knowing they've been "tricked". This is your key to success. Because, really, we're looking for a 100% garenteed outcome, right? Again, don't feel bad that the dating game is somewhat underhanded, and you will do things that normally some would call sleezy. I call this fighting for your girl and in the end, a man can ALWAYS fight for his girl!
1. Know yourself. What makes you such a great guy? Think about it, or ask your friend for help, and figure out why people like being around you. Are you funny as hell? Smart? Dependable for advise? A good listener? Get a list together and see what you can form your game plan around. You'll want to make sure these are the qualities you hyper-inflate about yourself. No, you don't want to make them look like a crutch, but they're the ones you want her to remember! Bring ypur A game with these. Next, figure out what turns people off/what your bad habits are. Try to shy away from these when you talk to her. Hide them, pack them away. Once she lieks you, you can address these (which won't be a problem, because her head will be too far in the clouds to care!)
2. Flirt. Be confident when you're around her. Don't just blab and ask her out. Remember, she's smokin' hot! She probably gets tons of guys that just go up to her and beg her to go out with them. You want to seperate yourself from them and look like the perfect guy. How do you do that? Smile, be polite, compliment her. Essentially, act like a boyfriend and not just a friend. Girls are big on impressions. If you're acting like a potential mate, she'll categorize you as a suiter. If you act like a friend, well buddy, that's all you're going to be. Be aggressive without out-right showing it through the small things and she'll pick up the hint. Do things like leaning in when she speak (if you're sitting), always be looking at her when she's speaking, use those good qualities to good use (make jokes, talk about interests, mention other things you have going on during the week even if you have to make them up, etc).
3. Tease. I call it teasing because this is essentially what you do. She's the lion and you're the meat and you want to dangle yourself as close as possible without her being able to reach you. Playing hard to get is not a bad thing, unless you out-right shut her out. Keep being flirty, but make yourself seme unavailable. Girls love the chase just as much as guys, they just don't show it outwardly like men. They want their man to come to them and if you resist their allure, they'll start putting on the charm themselves. But remember! don't go in just yet. You want to make her feel like all her charming powers are somewhat futile. You want to get it through her subconsious that you are not another guy she can wrap her finger around. I use subconsious because though some girls believe they're pure, no one is. They do it subconsiously, which is what attraction is about: using a girl's instincts against her to hyper-inflate how awesome you are to her. The only thing you need to watch out for is making sure you don't turn her off by being too hard to get, which leads up to my next point.
4. Read her. Girls have queues if they like a guy. Learn what these are! A few basic ones are hugging herself (not crossing her arms, learn the difference), adjusting her hair, touching her ear, smiling, shifting her feet, rubbing her legs together, anything squirmy or fidgity, really. It means she's ready to pounce (I wish I was joking) and that she really digs what you're bringing to the table. Let this go on for a couple conversations (maybe two, three at the most) before you pop the question about going on a date. If you've done it right, she'll be all over the offer and BAM! you've got your girl.
Yes, it's that simple. After this, you can do whatever you want, whether it's letting her jump your bone or forming a relationship. Remember that in the latter, you want to keep this up. Make yourself busy on purpose, mix up what days you go out as if you're too busy to commit to a schedual, leave her notes that tease her about how you miss her, and so on and so forth. You need to keep her interest level in you high if you want to keep her. But that comes with getting to know her on those dates, as well, so those are just some good examples of what normally works, not nessesarily what works on her. For example, my current interest loves to be showered with compliments, so heaping attention adn spending a lot of time with her is what she prefers. But that's all apart of reading your girl.
Hope my advise helps and you take it to heart!
