Ann Taylor and Katie Holmes are both in a phase of reinvention. Longtime lady workwear designer Ann Taylor is trying to appeal to a younger and hipper consumer, while Holmes continues to shed the lingering scent of Joey Potter in an effort to be taken seriously in grown-up land.

The collaboration between the two on the retailer's spring ad campaign (where Holmes replaces Heidi Klum) seems like a solid partnership.

"Holmes is a good fit to replace Heidi Klum. She's a 32-year-old working mom whose style has settled into a place that's clean and elegant but not too edgy or over-the-top and therefore accessible," says Fashionista Senior Editor Leah Chernikoff.
