We purchased 10 of these for a production of White Christmas.  They were a perfect length - right above the knees - and a perfect fulness.  The only problem was the binding on the bottom ruffle.  It looks great -it makes the petticoat look finished and high quality - but we had a few incidences where it came loose and would catch on things and pull off in long sections.  But it didn't happen on every petticoat and was easy to fix.
