Charlize Theron (in Boy. By Band of Outsiders) and Katie Holmes (in Holmes & Yang) are known for their chic style, and they both took a moment to thank the women responsible at The Hollywood Reporter’s second annual 25 Most Powerful Stylists luncheon at the Soho House in West Hollywood, co-hosted by Jimmy Choo.
