I was waiting to see if we had any official pictures of Margot wearing this outfit, however a long period of time has went by and there still aren’t any, so I am posting now!
In the half shots that we can see of Margot, she is wearing a Proenza Schouler Double Breasted Notch Lapel Blazer in Grey. This is not yet available for sale online. She is also wearing a ribbed top from Hanes, but I have yet to find the exact.
She also wore the matching Proenza Schouler Asymmetric Drape High Rose Trouser, also in Grey. This item is not yet available to buy online.
The main feature of this look, in my opinion, is the Rebecca de Ravenel “Long Treasures” Pearl Drop Earrings. The earrings are made from button silk with a gold plated pewter clip, brass chain, baroque pearl and fresh water round pearl. These are available for $375.
