Katie Holmes is taking the giant step of showing her latest collection for her fashion label Holmes & Yang at Lincoln Center during New York Fashion Week, Page Six can exclusively reveal. Sources said Holmes, who founded the line with her stylist Jeanne Yang, will show at the tents — the first time the duo will present their collection during Fashion Week. Tom Cruise’s ex-wife will be there near the end of the week to present the line, currently sold at Barneys. A source told us, “This is a big deal for Katie to show in the tents, under the full attention of the fashion editors and the glare of the media scrutiny. They could have done a small show elsewhere, so this proves she and Jeanne are very serious about their business.” Holmes is refocusing on her career post-divorce — starring in a play in November and two movies next year. Meanwhile, she’s still making time for daughter Suri. Friday night, Katie and Suri stopped by Artichoke Basille’s Pizza on East 14th Street. After ordering a margherita pie, an artichoke pie and some salad, little Suri ordered three fried Oreos for dessert. A source told us cute Suri ate two of the cookies and gave the third to an unidentified woman sitting next to her who accepted and ate it.
