Katie Holmes has gone from glamorous to unsophisticated. After turning heads on a recent red carpet appearance with her stunning black dress, the Jackie Kennedy of "The Kennedys" was snapped looking way too casual as she went shopping at Barneys in Beverly Hills on Friday afternoon, May 6.

For the retail therapy outing, the 32-year-old wife of Tom Cruise opted to go with a form-fitting red tank top. She paired up the belly-showing top with snug jeans and a pair of black flats. Going solo without daughter Suri, the actress was seen cruising around the shoe section of the store with a wallet in hand.

On Thursday night, May 5, Katie accompanied husband Tom to the Simon Wiesenthal Center's Annual National Tribute Dinner at the Beverly Wilshire Hotel, where he picked up the Humanitarian Award. Coming to the event, she looked stunning in a low-cut black dress with green satin waistband. She completed her look with black sandals and gold earrings with bright green jewels.

Katie's husband Tom was honored with the award for his support of the Jewish rights organization. Upon receiving the kudo, he said, "It's a tremendous honor. For me and my family this is really a very special evening and I look at what Simon Wiesenthal accomplished with his life, what this museum represents."
