There are two categories for trains, each with its own distinct advantage and disadvantage.
THE INTEGRATED OR ATTACHED TRAIN An integrated train is conceived as part of the gown and must be bustled.
There are three variations -
BUSTLE A bustle is achieved by lifting up the fabric of the train and fastening it to the rest of the dress with delicate buttons and loops, tiny hooks and eyes or snaps. For the bride’s sense of security, it is vital that all the stitching details be carefully reinforced on the skirt. It is also important that the bustling procedure be rehearsed several times. The versatility of an integrated bustle becomes more apparent after the ceremony, when the bride needs to maneuver comfortably among her guests. Be advised, however, that the weight and dimension of a bustle might add unwanted volume to the back.
FINGER LOOPS For some shapes, like narrow A-lines that cannot be bustled, a finger loop serves as a functional style alternative. A delicate loop of thread is attached to the center-back hem of the gown, enabling the bride to lift the excess fabric off the floor by slipping her finger through the loop. A skirt must be specifically engineered, however, to be worn in this manner.
CARRIED Like a cathedral veil, an extended train must be gathered up from the floor and draped over the arm. This graceful gesture is also a practical way to manage the train after the ceremony. Again, the skirt should be deliberately engineered to be worn in this manner.
