How short does my hair have to be for the Navy? - bang hair piece

I'm a girl and I had a haircut for Boot Camp. I will not do, because I'm sure you just hack and you'll look terrible. Works like a word, it is really? Inches wise? Can I bang? Then my mother brought me a piece of hair (BUN), so you can under my hat, or conclusion is a big no-no?
