Dax's Dress Selection Process for Kristen

Dax Shepard jokes about his involvement in Kristen Bell's Oscar dress selection.

Dax Shepard and wife Kristen Bell looked as adorable as ever on the Oscar red carpet on Sunday due in part (the couple joked) to Dax's fashion sense.

"[Dax] chooses everything for me," Bell joked, when asked if Dax had a say in her dress selection.

"We have a dry-erase board in the bedroom and I start throwing shapes up," Dax kidded. "We start with shapes. I said, 'Do you want to be triangular this year or circular?' They never pick circular."
