TV361 - 1880s Butterfly Detatchable Train. The Butterfly detachable train is a separate garment that attaches to any existing skirt, forming a bow or "butterfly" at the back of the bodice and then falling gracefully to the floor in poufs. This train was very popular in 1883-1887. It is perfect for a wedding gown, or turning a floor length dress into an evening showpiece. The large poufs at the back are created with pleats at the center back. These pleats are then placed over the lower edge of a long waisted bodice and hooked in place on the bodice itself. Additional pleats at the sides help create the butterfly effect. This train is very authentic, elegant, and easy to make. Sizing and Yardage Information: All the sizes are included, as given below.
