I love the color of that dress, though I'm not wild about the cut of the top/sleeves. And the coloring in the rest of the shot isn't too flattering. The color of the dress is enough to overpower the dislike of these other elements, though!
This beautiful gown is not identical to the gown of the Renaissance period yet it has a soft touch from the era. The velvet fabric and gold embroidery is something that the higher class would wear such as royalty.
