Aren’t we ready for that again? For some maturity? I have to tell you, I am sick and tired of hair down to there and crotch-high hemlines. It’s so obvious. For Fall I was really trying to bring back buttoned-up sexy — think Grace Kelly. So cool, so poised. She never reveals a thing and you can’t take your eyes off of her. I mean, watch “Rear Window.” That’s smart sexy; it’s interesting sexy. And it’s grown-up sexy. You want a tip on looking hot? Wear reading glasses and a fitted dress. Simple.
