Penelope Scotland Disick got her first dose of retail therapy!

On Wednesday, Kourtney Kardashian was photographed out and about for the first time with her daughter, born July 8.

Hitting a Neiman Marcus in Calabasas, Calif., the reality star, 33, carried her bundle of joy -- covered up with a blanket -- in a baby carrier, with her beau, Penelope's dad Scott Disick, along for the jaunt.

Blocking out the sun's rays with shades, Kardashian looked radiant and casual, giving a sneak-peek at her post baby bod in ripped jeans and a draped blouse.

"Nothing could prepare me for how hard I fell in love with her," Kourtney recently told Us Weekly of her little girl.

As for losing that baby weight? "I gained nearly 45 pounds," she told Us. "I'm 5 feet tall, so that's a lot. "While I'm here around the house, I just eat healthy."
