A standard black tuxedo is probably best, but a vest may be worn that may match the dress or the accent flower should be purple so that the two of you will match.
The dress has been found to be royal blue and black. It was found available for purchase on a British online retailer
The Navy blue or any other dark color.
Try to stick to a color pallet. You could wear some red, white or black to go all American or stick to pink, green, brown or purple. You should wear some pumps and possibly a high-waisted sweater that goes with your color pallet. If it has straps don't go heavy on the jewelry but if it is strapless heavy jewelry can be a good thing. Royal blue would be good with some silver, gold or grey jewelry but any other color could be risky. Don't wear boots with this dress or you might look like you got a dress, put a blindfold on, and randomly picked out a pair of shoes. If this dress is like Lady Gaga's and really is made to look like bubbles, forget what I just wrote and think about finding a new dress.
Winter white shoes & purse for subtle look. For pizzazz, use royal blue,, red or purple.
White is not normally considered a royal color. Purple is considered to be a royal color.
Roc royal favorite color is black my favorite color ;-)
