She didn't walk any shows in Milan, New York, or London, but the "plus size" model finally made her fall 2011 runway debut today at Posen's show. Renn has appeared in Posen's look books, and walked his show last season. We hope to see her make repeat appearances at Jean Paul Gaultier and Chanel — shows she also walked last season. Of course it would be nice if she booked a few more shows on top of that. See a complete runway slideshow of the fall 2011 Zac Posen show.
