On Tuesday night's episode of the Rachel Zoe Project, fans watched the celebrity stylist-turned-designer hit New York City to debut her namesake clothing line, which was a huge hit with the media and buyers.

Fast forward six months and Zoe, 40, was back in the Big Apple showing her second collection. And once again, fashionistas fell in love with her designs, which were a mix of breezy dresses inspired by "Brigette Bardot in  the south of France in the late '60s early '70s," she told Fashionista.

But despite being stressed out about her line, the new mom says that her 6-month old son, Skyler, has mellowed her out.

"Having my son now, it's actually given me clarity and making it easier," she told New York Magazine's blog The Cut. "My time is limited and so everything's more focused, and I'm actually way more efficient. And I'm also happy all the time."

The designer said those around her have noticed the change in her personality. "Everyone on my team has actually said to me, 'You're so calm!'" she said. "I'm like, I have Skyler. Everything people said [having a baby] does, it does."
