While she normally takes style cues from her fiancé's late mother, Princess Diana, the bride-to-be channeled her inner Jackie Kennedy, in the chic Jackie O. drape knee-length dress from Black Halo ($375, saksfifthavenue.com).
The former Suits star gave the tailored sheath dress a glam touch by pairing it with Aquazzura cutout suede pumps ($750, net-a-porter.com), a Gucci Dionysus suede mini bag ($830) and dainty diamond swirl earrings by Birks ($1,595).
Meghan's updo appeared to be a tad more polished than her signature messy bun. She kept the front pieces down to frame her face, and her makeup was light and dewy for spring with a glowing highlight on the bridge of her nose and cheeks for a natural look.
Her sophisticated 'do got us thinking... perhaps she has a new hairstylist? After all, a source told ET on Thursday that Meghan has "finally chosen a hairdresser" for her big day.
"[She] is working with the stylist to create the perfect look to go with her glam dress," the source revealed.
Unfortunately, it sounds like we're going to have to wait until May 19 to see what Meghan will wear and what type of hairstyle she'll rock as she says "I do" to Prince Harry. According to Vanity Fair, she will have two custom-made wedding gowns, and is planning to keep all details about the dresses top secret. The outlet reports that even Prince Harry doesn't know who the mastermind is behind her custom creations.
"Meghan can't wait to surprise everyone, especially Harry," a source reportedly told VF. "The wedding dress itself will be traditional and elegant. There is talk of some lace and sleeves and Meghan has been working very closely with the designer who has been sworn to secrecy."
As we patiently wait out the next 30 days, watch the video below to hear more on Meghan's regal fashion. And keep up with all of ET's coverage of the royal wedding right here as we count down to May 19.
