I'm attending a friend's wedding in March. The wedding is at an estate, starts at 4:30 and dress code is "black tie preferred" (???) Anyway I was looking at a few long dresses and DH said strapless isn't appropriate because the bride might be wearing a strapless dress so it should be reserved for her. I hadn't heard of that before. Obviously I won't show up in white or anything that looks like a wedding dress, but should I avoid strapless as well?
