As Elle said, avoid telling the stylist "blonde"....usually, unless he/she is skilled, that translates into orange/yellow streaks...which isn't bad, execpt for the fact that that's not what you're aiming for. Instead of blonde/light brown, request "honey" or "caramel" streaks. Oh, and if I were you, avoid getting "chunky" highlights, as they tend to look fake and are quite a nuisance when growing out. Stick to a more natural look :3
How about something like this?...
Good luck with everything!
