Meghan Markle is creating a new style era with stylist Jamie Mizrahi. First up: celebrity-favorite brand St. Agni.

In a photo shared on Instagram by longtime friend Ignacio "Nacho" Figueras, Markle can be seen chatting with guests over a candlelit meal. She is dressed in an open-back black dress by Australian minimalist-oriented label St. Agni.

Markle paired the streamlined gown with a halter neck and side slits with vintage Dior earrings and Mach & Mach heels.

Markle's backless dress was the second piece she wore from the designer that she incorporated into her new wardrobe over the weekend. Earlier in the day, she broke with royal (or former royal) convention by wearing a Heidi Merrick sundress with cutouts on the torso.
