I have longish shoulder length hair with long layers, dark blond with mid blond highlights. I'm aiming for sienna miller, but with dd I just bung it in a bun - I thought I looked boho but Dh said its more prim!!! I'm thinking if I get a few really blond highlights it won't look quite so boring - whadder you think?! Will I have slaggy straw hair and regret it?!
