They must let anyone sell on Wayfair. I can’t believe this company would make such a basic mistake. They must measure the fabric to be exactly the length you order then don’t realize you lose length when you actually hem it. I ordered 95 inch curtains, the package was labeled 95 inches and there was even hand writing on the fabric tag that said 95 inches, but when I measured them they were 91 inches. 
IF YOU ORDER MAKE SURE YOU ADD 4 INCHES TO WHAT THE SELLER LABELS THE LENGTH
