I should mention... even if they have to reprint alll their lines, I would not be worried about a price increase. It seems the cost of the greige goods, like the flood waters, has already crested. I have not heard anything about greige goods shortages in at least half a year, so no worries there either.
This flood will not have any larger effect, except that you will have a harder time finding Andover/Makower goods in the short term.
