"I actually just got measured for my bridesmaid dress," Madison, 30, told PEOPLE at the L.A. Confidential party Thursday for its May/June issue. "[But] I haven't seen it."
Wilkinson is in the midst of preparations for her June nuptials at the Playboy Mansion to NFL star Hank Bassett, and the final touches are still to come.
As for the often-dreaded bridesmaid dress, Madison is being patient. "It's in the very preliminary stages," she said. "They didn't show me a sketch or anything. Next time I'll get a feel for the shape, I guess."
