Work it, Katie Holmes!

Although it's now unclear when viewers will see her as Jackie O in a high-profile Kennedys mini-series  -- The History Channel has decided not to air it and other cable networks have so far declined to pick it up -- the actress, 33, looks every bit the fashion icon as the new face of Ann Taylor.

In the first ad from the campaign, the star gives a sultry look to the camera wearing a sophisticated blue pantsuit.

She told Women's Wear Daily of the brand: "I applaud women who are doing their best to be the best versions of themselves and who are working really hard. And I'm glad that there is a store like Ann Taylor that can offer amazing styles for the many different roles that women play."
