It was girls' night out for two of Hollywood's hottest young moms at the Forward by Elyse Walker and David Koma Dinner on Thursday, where Jenna Dewan-Tatum and Ciara both wowed in white-hot ensembles from Koma's spring 2015 collection.

Jenna, mother to daughter Everly, 22 months, and Ciara, mom to son Future, 10 months, dished on how having a little one at home has changed their style---and both seemed to agree that it has forced them to simplify.

When it comes to her clothing philosophy, Ciara reveals that motherhod has allowed her to relax. "I don't overthink things when it comes to fashion as much as I would have before," Ciara shares. "Now, I just kind of roll with things. And I'm like, whatever feels right, feels right. If you don't want to do it, don't do it. Don't overthink it."

The intimate dinner---which also included guests Camilla Belle, Gillian Jacobs, Brad Goreski, and more---took place at Soho House in West Hollywood, Calif., and showcased David Koma's new fall/winter 2015 collection along with a dress created exclusively for
