Between running her brand new wellness site, Poosh, and staying on top of mom duties with her three little ones, the eldest Kardashian sister is a busy woman. But that doesn't stop the 40-year-old from serving ample street style looks, and Kourtney Kardashian's slip dress was the latest must-have item in her sultry but minimalist lineup. While out-and-about with 7-year-old Penelope in West Hollywood, the CEO was demonstrating how to beat the heat with simplistic style, thanks to a formfitting emerald green slip dress.

Further proving the staying power of the silky staple that reigned supreme in the '90s, Kardashian took the nostalgia one step further with a pair of tan thong sandals. The divisive footwear style has also received a stamp of approval from younger sisters Kim and Kendall, swiftly becoming a summer staple for the fashion set from coast to coast. Kourtney's simplistic look was complete with tortoise shell sunglasses and a suede handbag, her raven hair styled straight and parted down the middle.

Penelope was serving a style moment in her own right, looking adorable in a pale blue two-piece outfit and Oxford shoes, while wearing what appeared to be a freshly chopped bob.

Style influencers and celebrities alike are in agreement that the effortlessly sexy garment is here to stay, because it's the type of unassuming staple that never really goes out of style. Edge it up with '90s-inspired grunge with combat boots, or nail the omnipresent prom-chic vibe with a pair of strappy sandals. Whichever sartorial direction you take, one thing's for sure: This timeless favorite will maintain a spot in your closet for seasons — and years — to come.
