Say a girl is giving you long glances and is checking you out while she's on the dance floor or at the bar. How do you approach them?

I was thinking of motioning them to come to me with my hand, like a come here gesture. Then I'd ask them what drink they'd like and then tell them to dance with me.

What suggestions do you have? What approaches are proven to work (that don't sound like canned bullshit)

In this situation, the "come here" hand wave you already described is the best thing I've found to work.

If you get so many girls "giving you the eye," you're probably like me in that you've got your fashion, grooming, fitness and body language to a really high standard and are giving off a very positive and friendly glow, which is good.

Another point is that you probably give off an aire of confidence, which is why waving her to come over to you will work like a charm--she sees an attractive (not necessarially good looking) confident guy and then you wave her over and expect her to come to you, which only proves that she was right about what she thought about you.

A few pointers on "come-here-waving"

1. When you see her, immediately smile, keep friendly eye contact and DON'T HESITATE FOR ONE SECOND to either non-verbally joke with her (waving, sticking out toungue, etc.)

2. DON'T BUY HER A DRINK, at least not right away! She thinks that you are a cool guy who can give her what the other, less confident guys can't, so don't ruin things by proving her wrong and showing her that you can't give her anything more than €5 for a cola!

Make sure you stay in the moment. Make a move within the first few seconds. If you wonder off and start pondering and engage with more eye contact you'll come off creepy. Huge turn off.

Yea, I need to make sure that she's eyeing me though, I can't just wave a girl over if we make eye contact once. So if I see her giving me 3 second looks twice or three times I'll smile and wave her over. I think that will work, I'll try it out next weekend.

3 second stares 2 or 3 times? I think thats a bit of an overkill. Remember you don't need an IOI before you make a move. Open a set smiling and strong body langauge. ppl make this mistake a lot. keep us posted! good luck!

Dude, don't get caught up in being 100% sure that you are the one she is looking at. First of all, part of confidence means just assuming attraction in situations like this, so "making sure" is a good way to show lack of confidence and ruin her attraction if you were the one she "was" interested in.

Secondly, with so many people, so many lights and so much alcohol in a club, if she wasn't checking you out and you wave her over, nobody will notice, least of all her.

you gotta go out more, if you are in a bar the whole damn venue is there for socializing, there is nothing special you have to say or do, if you are getting approach invites go approach with intent knowing that a girl already gave herself away before your approach, if no approach invites, you can approach all the same, what you say means very little (although saying certain things creates certain frames, and different frames support different functions)

the mind frame from which you are expressing yourself and how you are feeling and processing information, much more important then ''what'' you say, is ''how'' you are saying it, and why you are saying it in that way in the first place

from a personality point of view, confidence is your best friend, that is certainty, if you need 3 hints that a girl is checking you out just to go talk to her, then it would be interesting to see how congruently you can act in a way that seems confident and manage to escalate

to much worry about what will happen, and what is right and what is wrong, how to not lose and what to do, this all comes from a needy place

you have to channel your energy into a focus, be sure of what you want, what the girl wants and what you want are not the same, pay attention to how she feels, but what you want is #1, forget about her priorities, there are other girls, if what she wants is not in alignment with what you want, then you most likely have no chemistry and it's not important for you to impress her anyways, better to just move on and let her compromise for you, if she doesn't who cares, there will be better girls out there that possess what you are looking for in a partner, you just have to find them, go out and find what you were looking for, figure out who you are, display your personality, get to know her, see if she is what you are looking for, if not move on, if she is, move forward

TL:DR

doesn't matter, how you feel is more important, just know that she is into you and you want to talk to her, walk up and just say what's on your mind, say exactly what is in your head and what you feel at the time, be absolutely 100% honest

if you were to pick an opener that most likely expresses your frame congruently from your original post,
you would open with something like:

hey, I saw you over there and thought you were checking me out, who are you?

then take it from there, no plans per se, but rather an idea of what you want to do, just doing as you please and expressing exactly what is on your mind from moment to moment

i get glances/staring all the time that i literally do the same thing as said as above. i just say who are you? or something stupi like "yeah i know i look good"

being honest is the best thing you can do. Having shitty routines and tricks won't work. Unless you are just starting off its good to get some confidence but eventually you won't even think anymore.
