Perfect Hairstyle for Me?

I'm preeeeeetty sure I have a round face, and right now my hair is centimeter-past-shoulder length, it's wavy. I have bangs that swoop across my forehead, and I seriously regret getting them.

Anywho, I'm going to a hairstylist this Wednesday, because I absolutely despise my hair, and I love changing my look around. I'm gonna ask the lady what looks flattering on me, and best things for my hair, but I'm secretly crossing my fingers for a short look. Like beiber short. I hate having hair on my shoulders or touching my chin, it just gets on my nerves. I've had chin length hair before, and it looks terrifying. Since my face is a little bony, and my teeth are a bit crooked, I looked horrifying when I teeth-smiled. I think I hate my bangs most of all though. They never look right.

My point being, do you have any ideas for me? I would love something like this: http://www.beauty-cosmetic-guide.com/image/short2.jpg but without the side-burny part.

Remember, I'm not completely positive my face is round.

Any thoughts or ideeeaasss? (:

you could try something shorter at the back and longer on top of ur head and on the sides.
don't have a "bowl" haircut when it looks like some one has shoved a cereal bowl on ur head and cut round it.
something else which may look pretty and you could try before u go to the hairdresser is extensions.
you can also use extensions on ur bangs so they dont sweep accross your face and just tumble down like the rest of ur hair.
Merry christmas and happy new year!!
