Old Navy teamed up with Chandelier Creative for two goofy back-to-school spots starring Julia Louis-Dreyfus, who plays a wealthy mom looking for deals on clothes.

Directed by Hungry Man's Wayne McClammy, the two ads are the latest installments of Ms. Louis-Dreyfus's work with Old Navy. In them, she wears a Victoria Beckham-esque wig and asks the local schoolkids where they get their duds, embarrassing her boy in the process. "I look like our lawyer," the son says in one commercial. "Exactly," Ms. Louis-Dreyfus responds. After finding out where the other kids get their clothes, the mom and son pair decide to go immediately to Old Navy for deals.

The spots, called "First Day of School" and "Picture Day," will run though August and September.

A 60-second version of "First Day of School" will run in cinema, and other elements of the campaign will run across social media and radio.
