I skipped a lot of this thread because it seems to me like some people here are forgetting you're only 15. It's allowed to be 15, you are NOT stupid.
A lot of advice you've been given would be spot-on if you were an adult. It doesn't matter that the advice is right, and that you'll learn to understand the advice in some years. The point for you right now is that you ARE 15, and we can't expect you to have the mind-set of an adult.
Your concerns are normal for your age. Practically all teenagers are worried about being labelled. What friends think is incredibly important at this age, something those of us who are older tend to underrate. I've got a 15-yr-old son, so I get a daily reminder of what it's like.
It sounds to me like you're wondering about asking someone out who appears to have a different lifestyle, and you're uncertain about how that will be received. Doesn't matter that you're so young, and the girl you're interested in is even younger - we've got to remember that your feelings are real to you, even though we know this is just the beginning of a long life of relationships.
This sort of experience is the kind of thing you'll go through now and then. The point is to learn from it. Your values are being challenged, you're wondering what stand to take, and what it says about you. Asking those of us here for opinions is (hopefully only one

) way of testing the moral waters. In the end, you have to rely on your gut.
Short version: Don't feel bad about the way some of the advice here has been worded. A lot of it is good, and you'll understand it more over time. For now - good luck.
Great post - seconded. I'd like to add to it, if you don't mind

, from a different perspective perhaps.
TSE, I've only scrolled through this thread and haven't read into every single detail. It's unbelievable how some people have (over)reacted to the "label" part. And, if you call it love or not, it's irrelevant. You can ask her out, sure, if she says yes, great, and if you start a relationship, you should both discuss what expectations you have from it. If it doesn't work out, fine, it happens to everyone, of all ages.
If you do get labeled for going out with her, it makes perfect sense that the people doing that are wrong. In some ways, yes, their way of judging things (labeling) may be similar to yours, but they act on their impulses and have bad intentions, while being fully aware of it. They're obviously either insecure, or just following the majority. Compared to you, they probably think their opinions matter a lot more than they should. Or they just don't care what effect their opinions might have on other people. Maybe they're blindly echoing what everyone's saying these days - emos are laaame </Cartman voice>. And that's all they are - opinions, which you probably don't even share - you don't come across that way, which is why I think some people might have overreacted in this thread. The opinions you hear from people you know don't say anything about you; determining what you are and what you like is your job, and on this subject I'd like to echo what
annk said, follow your gut feeling. I mean, do you really care if she's "kinda" emo? You, personally, after having taken everyone out of the equation? Or would you agree that it's kind of unfair to judge her based on her appearance?
If you agree, just walk up to her, it's a question after all. If she says no, fine, there's a variety of reasons why she'd say no. You could always ask her why, maybe
her friends think of
you as the uncool type - see a trend here? See what this kind of thinking does - it creates obstacles, and you end up missing out. But don't worry, at that age, it's appropriate, as far as I'm concerned. On the other hand, if she says yes, make sure you're actually honest to each other, no point in staying in a relationship if you don't actually connect. If it doesn't work out, I don't see the problem in staying friends, if it makes things less complicated.
Either way, if you're not ready, don't feel pressured. If this post added more confusion, it would probably be best to take a step back and wait it out. There's always later.
