Reality star Kourtney Kardashian and partner Scott Disick welcomed their second child Penelope Scotland Disick in July this year. Working hard to shed all that extra post-baby weight, Kourtney was recently seen flashing a slimmer profile with a little bit of extra help from Spanx.

She may not have gotten back to her earlier shape as yet, but she sure knows how to keep the weight under wraps. The 33-year-old was spotted by The Daily Mail stepping out for lunch in Miami dressed in a knee-length, patterned beach cover up and she flashed a tiny bit of Spanx shape wear.

Carrying four-month-old Penelope, Kardashian teamed the top with nude flats and left her long, glossy tresses loose. Perfect for a laidback look, she kept her makeup minimal and shielded her eyes with stylish, oversized sunglasses.

This is not the first time that Kardashian has been seen wearing the shape wear. She recently flashed a pair of Spanx under a green gown during a photo shoot. Sisters Kim and Khloe Kardashian have also been spotted wearing Spanx a number of times.

Launched in 2000, Spanx is a popular choice among models and celebs. Considering that they are constantly in the media glare and are expected to look good all the time, Spanx keeps them looking slim and fit. A-list Hollywood celebs like Gwyneth Paltrow, Jennifer Garner, Oprah Winfrey, Jessica Alba, Emily Blunt, Katherine Heigl and many more swear by the shape wear.

Michelle Trachtenberg, well-known for her role as Georgina in "Gossip Girl," told dailymakeover.com that the brand’s tights were a staple on set. “I love Spanx tights! I wore them on the set of Seventeen Again and Gossip Girl!” Katherine Heigl is said to have worn the shape wear even under her wedding dress.
