NEW YORK - Katie Holmes debuted a stylish bob this past summer and, all of a sudden, her 180-degree reinvention from low-key twentysomething to sophisticated arm candy of Tom Cruise seemed established — in this case, the hair really DID make the woman.

The "Dawson's Creek" alum recently updated her look, displaying eye-grazing bangs at a red-carpet event in Germany. Photos of the china-doll haircut swept through cyberspace, as Internet critics weighed in: some loved it, some hated it, and some sniped at its uncanny resemblance to the 'do of her 1-year-old daughter, Suri.

While long hair remains the norm in Hollywood, a handful of cropped cuts — versatile variations on The Bob — are making bold statements, from Holmes' classic coiff to Victoria "Posh Spice" Beckham's sleek style to pop star Rihanna's edgy mane makeover.

As for who triggered the bob's rebirth among the rich and trendy, Paves, whose celeb clientele includes Jennifer Lopez and Jessica Simpson, points the finger at Beckham.

"It would be silly to say that she was the only person in Hollywood wearing a bob, because, you know, by all means, she was not — but hers definitely drew the most attention at that time," he says of the media frenzy over the Spice Girl's drastic 2006 hairdo: stacked in the back, angled at the side.

Rihanna put a severe spin on The Posh last spring with super lopsided layers — a smart way to stand out, given the buzz surrounding her megahit "Umbrella." Holmes — Beckham's B.F.F. — took a more moderate approach, as did Christina Applegate and Hilary Swank. Christina Ricci recently popped up on the red carpet with an ear-skimming bob.
