What sort of facial hair styles would look good on teens?

Ok, so I'm a 15 year old male, but I look like I'm about 16-17.

It's gotten to the point where I need to shave every day or two, and I've always though growing some sort of facial hair would be cool, even if I only kept it for a few weeks. I'm quite tall, with dark coloured hair. I think it's black, but under certain lights, it can be a very dark brown. Although it's probably easier to just say my hair is black. I also have blue-green eyes, if that makes a difference.

So, any good facial hair styles? Preferably one that would look good on a teen? Any help would be appreciated.

Thanks.

(Also, if you want to suggest a goatee, feel free, but that might be a little hard for me, since the hair that connects the upper lip and chin hair doesn't grow as fast as my other hair)
