Kristin Cavallari stepped out on Saturday to celebrate C Wonder’s first birthday in New York City.
At the event, Cavallari told PEOPLE that it was “good to have an afternoon away to unwind.”
The former Hills star was on a mission to find the perfect coat. She tried on several styles and danced in the mirror as the deejay played music.
The proud mom also doted on her son with fiancé Jay Cutler, noting his recent milestones.
“He’s making all kinds of noises and laughing and smiling all the time,” she said. “He is a very happy baby. He loves to talk making lots of different noises and then he laughs and laughs.”
