Many busy mothers of two children may not be able to fit into a tiny shift dress, less than three months after giving birth.

But Kourtney Kardashian was an image to make women across the planet feel very envious as she filmed scenes for her reality TV show on Friday.

The 33-year-old was out with her son Mason, two, and her step brother Brandon in Miami, Florida.

In the absence of her partner Scott Disick Mason’s uncle accompanied them to a children’s toy and clothing shop.

Even though it was just a casual outing for the boys, who wore black T-shirts, Kourtney was dressed to impress in a 60s style halterneck frock.

The item featured a beige lower layer and black top, which she paired with two-tone shoes, the clothing even co-ordinated with her large tote bag.

The brunette wore her hair super straight to be on screen and donned oversize circular framed sunglasses from Prada.

Even though her newborn girl Penelope was not present, she appeared to be picking up some bits and bobs for her new addition to the family.

Brandon, who is Bruce Jenner’s son from a previous marriage to Kardashian matriarch Kris Jenner’s, was on hand to help her pick out a baby carrier, as was an enthusiastic Mason who helped test out toys.

On exiting the Genius Jones shop in the holiday hotspot, Kourtney was laden with large bags from the spree.

While she has been putting a lot of effort into her workout routine to get back into pre-pregnancy shape, her eagerness to enjoy retail therapy in heels will certainly speed up the calorie-burning process.

The group later joined Kris Jenner and Kim Kardashian for a meal as they recorded more scenes for their forthcoming series of Kourtney and Kim Take Miami.
