What is a "train"?
A train is a long, flowing extension of fabric that trails behind a garment, typically a wedding or formal dress. The train is attached to the back of the garment, either at the waist or the hemline, and can vary in length from a few inches to several feet. Trains can be made from a variety of fabrics, such as tulle, silk, or satin, and can be embellished with details such as lace, beading, or embroidery. While trains can add a dramatic and romantic effect to a dress, they can also be a practical consideration, as they can make it difficult to walk or move around freely. As such, they are often bustled or gathered up during certain parts of an event or ceremony, such as the reception or dancing.
