I think this Dior gown has a lovely, elegant style and flow. However, I would have wished to see it in a more colorful shade. Perhaps something soft and subtle in lilac or light, pale green, or even pale pink. I don't think this cream or sand-like shade does much for Meghan's complexion (at least not in photos).
I do like the shiny, silvery detail on the sleeves, but it's not very visible except in close-ups. I think it would stand out more on a colorful dress in a soft, light-colored shade. Of course, there's nothing wrong with this selection, but I'm not very enamored of the overall look in this shade. It looks fine on Meghan, but I think it would have looked better in a soft color. But I suppose beige and soft cremes are part of her basic monochrome color-palette aesthetic.
