consider me an idiot, but this seems very survivable given what is displayed. the foot that has weight on it is on the dress but the foot that is traveling is free and clear of obstruction. it will continue on to its final destination although probably considerably shorter than her normal stride; but judging by the cut of the dress that will not be greatly affected. and as soon as she transfers weight her skirt will be freed, and she can continue on her merry way. so unless we know that she fell what really is wrong?
