So we know who's walking Meghan Markle down the aisle as part of her May 19 wedding to Prince Harry, we know who's in her wedding party and we know how to watch it all go down.

But, let's get down to brass tacks — what the hell is she wearing? What does Meghan Markle's royal wedding dress look like?

Glad you asked.

While we likely won't know the ins and outs of Markle's gown until she officially unveils it at Windsor's St George's Chapel, the internet — trusted sources included — has got some ideas.

According to the United Kingdom's Telegraph, Ralph & Russo are the likely designers of the dress. Still, Burberry, Erdem, Stella McCartney and Roland Mouret have been rumored to still be in the running. The site says Ralph & Russo have "become known for their elaborate, frothy and immensely glamorous couture gowns." (Check out an example from the label's 2017 showing at Paris Fashion Week below.)

Markle wore a gown designed by the label for her official engagement photos, which is a big hint that she'll stick with the brand for her wedding. And while that piece was estimated to cost 56,000 pounds, the wedding dress could be nearly double.

And while Ralph & Russo are known for theatrics, it's likely they'll take a more minimal approach to Markle's gown if they are, indeed, designing it — Markle's style has so far indicated that she errs on the side of classic shapes and silhouettes without too many bells or whistles.

Brides, meanwhile, asked a collection of high-profile bridal designers what they predict Markle could wear, and while Caroline Castigliano predicts "I think Meghan will wear a gown that is classic yet sensual and stylish with a modern highlight...It would be a nod to tradition, which would be expected and required from the royal household, but would also show her personal sense of style," Rime Arodaki foresees: "Her style is very sleek, a lot of twisted bandeau, clean cuts, and knee-length hems, so I imagined Meghan's added freshness to the royal wedding dress."
