I've been seen in skimpier things than that, go for it. If your going to set a example it might as well be a bad one that way people will remember it. T
Only issue is you probably wouldn't want to wear the dress around the sexy pool, but all of those suits are not only allowed. They are required.
My girl has the same Black dress, she will be wearing it. Last time she wore only a White Boa, for white Night, nothing else maybe some lipstick a shoes. Be brave never had a problem.
