Rachel Zoe designer Beverly Hills shopping

The earth must have stopped moving yesterday ... super-stylist Rachel Zoe wore jeans and a t-shirt!

The uber-fashionista pushed her baby carriage through Beverly Hills as she stopped in various boutiques to shop and through it all, she was wearing wide-legged jeans and a simple, black V-neck tee!

Could it be postpartum hormones getting to Zoe or maybe motherhood is making her style a bit more practical?
