Gwen Stefani in Plaid Suit Pictures in LA

Gwen Stefani was decked out in a festive suit yesterday for an afternoon of shopping around LA, including a stop by CVS and a trip to Bristol Farms for groceries. She's finishing up last-minute errands ahead of the holiday weekend, which she's already started prepping for. Gwen is just one of many celebrities getting into the spirit and she picked up a few ornaments and decorations with Kingston and Zuma at the beginning of the month.

The Stefani-Rossdale family is winding down a big 2011 that included plenty of adorable moments. They traveled to the Cannes Film Festival, hit the snow in Mammoth, CA, and even had a playdate with Angelina Jolie and her kids. Gwen and Gavin's style was also in the spotlight, landing them among the most fashionable couples of the year.
