New Year's hairstyle

I want to get a new hairstyle for the New Year. But what? Any suggestions anyone? I’m so bored of having this long hair of mine. I thought of cutting it short till the shoulder length but I’m afraid I will look chubby and fat.

I thought of curling before. But curls usually make people look matured right. I tried it once but it was just temporary just for my prom night, and it looks like this:

I'm the one in red

Then again, it's hard to maintain curls and I am still studying. I'm sure after a while I will get bored with it too. Maybe I will just go for the shoulder length hairstyle. So will wait and see!
