Drumming up some business for her latest venture, Kristin Cavallari was on hand at the WWDMAGIC 2013 event in Las Vegas on Wednesday (February 20).

Proudly displaying her new line of shoes with Chinese Laundry, the “Hills” star looked professional in a shimmery grey skirt and a sleeveless black blouse.

After taking care of some press obligations, the blonde beauty took time to sit with fans and sign some autographs.

Keeping busy with all her projects, the new mom recently launched a versatile collection of jewelry in partnership with GLAMboutique.
