Chic baby on board! Kristin Cavallari shared with fans via Instagram on Friday, July 17, that she's starting to put more of a fashion focus on her pregnant physique.

"Dressing for the bump," the Hills alum, 28, wrote, alongside a snap of her outfit of the day. Cavallari's monochromatic combination includes a pair of dainty white lace shorts that show off her lean stems tucked into a pair of open-toe suede booties.

Up top, the shoe designer wears a black silk button-down shirt and carries a leather satchel to her side. Cavallari gently cradles her bump with her left hand in the photo. "#pregnancystyle," she concludes.

Cavallari's latest pregnancy update comes a week after the Balancing in Heels scribe announced last Thursday, July 9, that she and her husband, Jay Cutler, are expecting a baby girl.

"The boys are so excited for a little sister!!!!!!" the beaming mom wrote on her app, alongside a photo of her holding a pair of tiny pink Chucks while embracing her husband.

The NFL hunk and former reality star are also parents to sons Camden, 2, and Jaxon, 14 months. Just this past week, Cavallari posted a photo of her diaper-clad youngest dragging a Swiffer in their home. "The cleaning crew," the smitten star captioned the cute snap.

Pretty soon, Jaxon will have to get accustomed to becoming a big brother like Camden. At an event this past May, Cavallari gushed about her eldest to Us Weekly. "Camden is a really good big brother," she said. "He's very protective and very sweet, But he also gets a little upset when Jax tries to take his toys and messes with his stuff. He gets a little territorial with some stuff, so it's kind of funny."
