I like the dress and have some similar. Get your husband to take a picture of you wearing it, it is a better way to see how you look. If you are confident it looks good then keep it.
This. Put it on with your hair done how you would wear it, the shoes you would wear and get some photos taken from all sides. Failing that use a full length mirror. Sometimes things don't hang the way we expect them to, and give you an entirely different shape (which could be good or bad). If you like it, wear it.
Mr A sometimes dislikes things I buy because he can't imagine what it would look like on, with shoes, jackets, etc. Usually once I'm wearing it he changes his mind.
