Margot Robbie was undeniably glowing at the Hot Girl Walk in Los Angeles on Friday 11/11. 15. Having given birth to a son with her husband Tom Ackerley last month, it's no wonder why the stars are all soft smiles these days. The Oscar nominee took a casual afternoon walk with some friends in a black dress with black puff sleeves with a square neckline. The frock also allowed me to incorporate the Holy Grail I'm always looking for when buying a daytime dress: pocket.

It's hard to say from a distance, but I'm pretty sure the mini dress is a cotton poplin design from Ciao Lucia. The LA-based brand is known for its deep catalog of wearable, feminine dresses — many of which resound for less than 500. Olivia Rodrigo is also a fan of this line, so it is not difficult to imagine that their dress is in the closet in the lobby. Alternatively, New York designer Nikki Chessin offers a very similar silhouette with both puffs and ruffles.

Robbie accessorised her crisp dress with black ballet shoes, a gold herringbone chain necklace and black oval sunglasses that leaned on Mary Jane's trend. The accessories matched her previous baby's style book, when minimalist shapes and neutral tones dominated her wardrobe.

According to Emma Childs, editor of Marie Claire fashion features, the best Mary Janes can be found from brands such as The Row, Rosie's and Larroudé. But the closest match to the Barbie Star's rounded black leather Mary Jane flat comes with an ultra-thin, stretchy strap. As the sunny walk in the lobby clearly shows, these shoes were made for walking.
