These days, not as many wedding dresses have trains, at least in America. Many brides have realized that extra fabric on a wedding dress ends up costing them a little more. That, plus the fact that they cant see that part of their wedding dress all that well, and it drags on the ground, has made the train an extra accessory that some brides decide to eliminate.
However, theres nothing as elegant as the train on a wedding dress. Every royal bride has a long train as an integral part of their wedding gowns; that shows the regality of the bride, who deserves to feel like a queen on her special day. Wedding trains bring glamour, especially if it looks like it was part of the original design, as opposed to an add-on.
