I don't think the role of style is different for a woman of any age. Style, to me, is about experimenting with what gives you pleasure, a joyous expression of imagination. I emphasize joyous because too much is written about fashion that takes the pleasure away - clothes that make you look thinner or clothes that make you look younger or, horrors, clothes that make other people envy you or that - double horrors - are "age appropriate".
