It's stunning on you, Una. Perfectly elegant and subtly alluring as someone said up there on another page of comments. I like the styling ideas gryffin had. Even if it's your go-to elegant occasion dress, it could be worth it. I could see it working for years hence. The shoulder detail adds to the elegance of the design, imo. It's a flattering little detail you wouldn't find in a less well-made dress.
P.S. a styling option for later on might be to wear a bright slip-dress under it, to show through the sheer panel.
