Sarah Jessica Parker in Current/Elliott The Ranchhand Overalls in Wanderer
She chose the Ranchhand Overalls in Wanderer which are a bit slouchier and have a bit of distressing. She paired them with a pair of wedge sneakers and a slouchy Henley shirt. This is definitely a more casual look and I can see her wearing them on her many school runs with her kids. You can buy Current/Elliott online from Shopbop.com.
