I need advice quick

Your chin length hair sounds pretty. I am a guy and I love bob styles. Nothing like a pretty girl with a pretty bob. Actually I have my hair cut in a bob below my ears with bangs and I love the movement and versatility. If you want to go shorter than chin length try just below the ears like mine and maybe add a little layering. It really depends on your hair and face. You could even go shorter to just above the ear with a buzzed nape. Let me know what you think and what you choose.
