I love the look of the curtains, however the length is not 84". I'm not sure why they are listed as 84" when I measure them they around 81-82". This is a big difference when hanging curtains, as they look quite foolish hanging above the floor. I haven't purchased many items from Wayfair, so maybe this is my fault. Are the products usually "slightly imperfect'? Is that why the price is lower?
