Answer:
I'm not a professional, but when i get my hair cut i usually pick a style and put it against my hair/face and see whether or not it will look good. You can also explain your idea to your hairdresser and they can give you feedback on whether they think you should get it cut like that, and what they think you should do to your hair. Don't be shy, hairdressers want to know specifically what you want because they don't want to mess up your hair and you don't like it. and most hairdressers like to answer questions as such! sorry if this answer is not correct, but good luck and i hope your hair will look great when you do get it cut! ♥
