The reality TV sisters released the first pictures of their new line of baby clothes yesterday, reported the New York Daily News.
The 30-piece collection includes gold polka-dot leggings, little dresses covered in butterflies and leopard print outfits.
"It was mainly Kourtney who was the inspiration, but as I got pregnant, I started to chime in," Kim said about the collection.
The line also has Twitter, Instagram and Facebook accounts. The collection will go on sale online from March 15.
