It's a big day for Prince Harry and Meghan Markle as they officially tie the knot and become Duke and Duchess of Sussex, but it's an even bigger day for lovers of royal fashions because we are looking at The Dress. There hasn't been a Dress this Dress since Kate Middleton's Dress, and before that, Princess Diana's Dress, which was so big it was really more like three dresses, but we digress. The point is, Markle wore Givenchy Couture, designed by Brit Clare Wright Keller, who "last year became the first female Artistic Director at the historic French fashion house Givenchy," according to this frankly very long royal blog post. And it's gorgeous!

Arriving at Windsor Castle, Markle looked radiant with her hair pulled back and up, a sparkling tiara on her head, and a sheer veil over her face. Tasteful diamond earrings completed the simple and elegant look, not distracting from her bright smile or the white silk boatneck gown with three-quarter-length sleeves. Or, as the royal blog-poster eloquently put it, "the pure lines of the dress are achieved using six meticulously placed seams. The focus of the dress is the graphic open bateau neckline that gracefully frames the shoulders and emphasises the slender sculpted waist. The lines of the dress extend towards the back where the train flows in soft round folds cushioned by an underskirt in triple silk organza. The slim three-quarter sleeves add a note of refined modernity."

The flowers stitched in the veil represent the many nations of the Commonwealth. It took two pageboys to hold up the long train of the veil as she processed down the aisle on the arm of her now-father-in-law Prince Charles, a picture of serenity. Sorry, getting weepy, pulling it together, okay, we're good.
