I am bored of my mid-length hair and am thinking of a short style (but definitely not a short bob as that looks awful on my hair). I have lots of hair, very slightly wavy, can be frizzy, with highlights. I am thinking something like Yasmin Le Bon had back in the early 1990s. My main concern is that as I am about to turn 42 I don't want my hair to look like frumpy mum hair! Any suggestions?
