My last haircut was a loooong time ago. My hair has gotten freakishly long.

I'm headed to a wedding next week and I really want to get it cut this weekend. My hair is currently very blah and I want something with more shape.

I'm thinking to get the overall length brought up from butt length to boob length, and then some face framing layers. My hair has a natural wave but it's so heavy right now that it pulls the curl right out. I'm hoping that shortening it and giving it some layers will help me achieve some beachy bouncy waves.

My only worry is that I have a really round face, and I'm afraid that I'm going to screw up and make my face look wider. Any thoughts? Do you think something like this will work on a round face?
