Bustles are usually associated with a design that is included in the back of a skirt. Bustled skirts can also have that look in the front as well. Whenever you see a skirt that has a bunched-up look either in the back or all over it, this can be considered a bustled skirt. Bustled skirts can also be shorter in front and much longer in the back, which truly accentuates the character of the bustle.
