The style of the masquerade dress holds the key. It is important for you to determine whether you want to go for an 80s prom dress or stick to a contemporary masquerade dress. Once you have settled on what you are going to wear, it is important that you determine certain essentials.
Though it is a prom night and everyone will be wearing masks, do not attempt anything extraordinary, which may have you stand out of the crowd for the wrong reasons. Always refer to the dress code that has been mentioned on the masquerade invitation and follow the same, while trying to fit in yet stand out.
A safe combination for a masquerade party would be a silver-colored mask with feathers on a black or red dress. A mask can be bought first while then working out your dress according to the way it looks. That way, you're sure to have both the dress and mask complement each other, where those who want to go the quirky route, can mix and match colors.
Once you are sure about the things you need to sweep your admirers off their feet with, finding a perfect masquerade dress will not be an ordeal for you!
