Katie Holmes and Victoria Beckham will never end up in Us Weekly's "Who Wore It Best?"
"We go to the same events, and we'll call each other to ask, 'What color are you wearing?'" Holmes, 33, explains in the December issue of ELLE. "I'm always interested in what she's liking for the season."
Holmes isn't the only celebrity who's a fan of Beckham's in-demand designs. "When we have Victoria's stuff in the studio, it's the first thing Cameron Diaz tries on," stylist Rachel Zoe, 40, says. "But any woman would feel sexy in her dresses."
Beckham remains modest about her sartorial skills, telling ELLE: "I just create what I want to wear. I make what feels right."
Though her success in the fashion world was once attributed to her celebrity connections, Beckham insists her designer BFF Marc Jacobs was actually the last to know about her design ambitions.
"We went out to dinner one night, and he said, 'I saw that you put out a collection,'" Beckham, 37, recalls. "I felt embarrassed to tell Marc Jacobs that I -- me, ex-Spice Girl, married to a footballer -- was creating a fashion line."
