Fringing was as if a single, defined element was plucked from 1920s fashion revival, elaborated upon and then modernised. It always went in and out of fashion. How you want to bring it up is all depends on style and themeing of the piece. The appeal of fringing also owes a lot to the way it moves, so pay extra attention in choosing quality fabrics that shimmy and shine and do not clump unattractively together.
A pair of long, toned legs work wonders for a short fringed skirt just like Katy Perry.
