Lookin' good!

Kristin Cavallari showed off her amazing post-baby body in a sexy snapshot on Instagram Thursday, flaunting her slim silhouette in a cream knit Riller & Fount maxi dress and peep-toe booties from her Chinese Laundry collection.

"The Hills" alum completed her chic ensemble with a Hat Attack hat and a backpack from The Row.

The reality star took to her own Kristin Cavallari app to debut the first photo of her 2-month-old son, Jaxon, earlier this month.

"Speaking of Jax, here is my precious little peanut..." she wrote along with the cute candid.


How adorable!

Cavallari and her hubby Jay Cutler welcomed baby Jaxon back in May.

The blonde beauty recently opened up to E! News about losing 20 pounds in just two months. "I started working out when Jax was three weeks old," she revealed. "I've been working out four to five times a week for 30 to 45 minutes at home, doing tons of leg work like squats, lunges and lifting weights. I want to start Pilates again to focus on my core. I'll probably get back into it in the next couple weeks."

Motherhood certainly looks good on Kristin!
