Reese Witherspoon looked spunky in stripes as she shopped in LA on Tuesday!

The actress worked a cute colorblock striped sweater with sunglasses, skinny jeans and short boots. Adorable!

Over the weekend, the always-mature Reese threw a birthday party at Disneyland for son Deacon, 8. What we love is that Reese and ex-hubby (Deacon's dad) Ryan Phillippe co-hosted the soiree! Reese always puts her kids first -- new husband Jim Toth was not at the event, giving plenty of room for Ryan and Reese to get quality time with their kids (daughter Ava, 12, was also at the party.)
