Katie Holmes red carpet century city Beauty Culture Event Annenberg Space Photography

Katie Holmes is back from taping one of Oprah's final shows in Chicago ... just in time to hit the red carpet at the Beauty Culture Event and exhibit in Century City for Annenberg Space Photography.

The exhibit "provides a seminal examination of photography's role in capturing and defining notions of modern female beauty and how these images profoundly influence our lives in both celebratory and disturbing way."

Whew ... now that we understand that, let's focus on Katie's beauty. Tom Cruise's wifey is wearing a Madewell dress with a Lanvin blazer. She is certainly the definition of modern female beauty! As for the exhibit, it will be open from May 21 to November 27.
