Wow! You look so pretty in blue, and that cut is doing some amazing things for your figure.
This dress is ticking all of the Dramatic Classic boxes, the sheen, the substantial/rich fabric, clean/narrow lines of the silhouette, the geometric design, the color blocking, asymmetric neckline, but IKWYM about the 'is it me' factor. I feel it looks best with out the jacket because of the neckline, but ya gotta do what ya gotta do if it's cold. The plot thickens!
