HELP!!! New Hairstyle? Highlights?

  1. I am wanting to cut my hair to about just around my shoulders and put some platinum highlights in it (its dark brown now) Im thinking pretty light on the top and leaving it brown underneath and putting some chunky layers in it. Anybody know what im talking about? Have you need any pics of this?? Im looking for something to take to my stylist and im kinda lost, lol
