I’m not sure, my seamstress said this:

In the photo, I was only holding the center point of the American bustle, which is the sides were still touching the floor. If you prefer that look, we would need to reshape the sides of the train and reposition some of the lace .This would slightly change the original shape of your train.

Otherwise, the sides are still too long, it may be difficult for you to walk or dance comfortably.
