Katie spent the day in skintight leather trousers, paired with a black jacket and black polka-dot pumps . A messy updo kept things casual as the star prepared for a preview event in New York on Tuesday for the Fall 2011 Holmes & Yang collection - the line she designs with her stylist Jeanne Yang.
The evening saw Katie ramping up the glamour and hitting the town for a girly evening out in a long pale grey Lanvin skirt, pale grey Nina Ricci top and a short sleeved white fur shrug. Natural makeup and loose curls kept the look simple but stylish.
