What is it about this silk military-inspired slip dress by Self-Portrait? While it doesn't feature sheer details like many of the label's designs [1] do, it's so darn good, both Olivia Palermo and Gigi Hadid have it. While Gigi wore like a model [2] and had a total street style moment [3] in her number, revealing her long legs through the skirt's slits as she walked, Olivia took her lust-worthy maxi onto the red carpet at the Audemars Piguet celebration.

Leave it to Olivia to pile on unexpected [4] yet festive accessories that were perfect for the season [5]: a shimmering beaded box clutch, her go-to chain-link bracelet, matching chunky rings, a watch, and auburn crocodile pumps. She left her neck bare, just as Gigi did, drawing attention to one casual detail: a set of pockets.

Read on to see how both Gigi and Olivia wore this Self-Portrait stunner [6]. Then what better way to ring in the weekend than by shopping for the one holiday look that's approved by your two favorite style icons?
