What type of haircut should I get to downplay some of the strong features of my face?

I have a square shaped face that I would like to soften up. I have a widows peak that I would like to hide. I currently have a longer hairstyle with side bangs, but I always get a colic because of my widows peak. I'm not sure if my long hair is helping me square shaped face either. please help!! :) thanks!
