Katie Holmes at Holmes & Yang Harvey Nichols Event in London

Katie Holmes made her latest fashionable appearance in London to preview her new collection for Holmes & Yang at upscale department store Harvey Nichols Tuesday evening. Katie was joined by her design partner, Jeanne Yang, as well as Heather McQuarrie to pose for pictures amid the racks. Katie first popped up overseas yesterday, when she attended the Giorgio Armani Privé Haute Couture show. She was coming off celebrating husband Tom Cruise's birthday with a family-filled weekend in Miami, where she and the kids threw him a surprise party. Katie Holmes sported a bikini while Tom and their daughter Suri were decked out in festive face paint for a Sunday by the pool before the actress jetted off for her solo trip abroad.
