Body help, desperately need advice. ?

I just came home from the beach and realized that my face, arms and legs are all quite thin and in good shape but then my stomach is quite fat and whenever I sit down there's like 3 rolls of fat, it looks unattractive and makes my body look out of proportion.Any time I put on weight it goes straight to my stomach and cause it's summer I just want to get rid of the extra weight, is there any way i can do this quickly? cause it's even getting me down. I'm a size 2 and about 5"1 and around 110lbs maybe it's just me being paranoid but I just think it looks strange.
