If there is going to be good buying and selling, buyers must provide accurate measurements.
I had a seller provide measurements for some pants. The cuff opening was off by a full inch, the waist 1.5 inches. When I PM'd they replied, "Those are the measurements off the brands website". WTF???
At least the seller will take them back, because they are not as advertised. But it is a huge waste of time for everyone and the added expense to both parties for lost postage.
Come on guys, take careful, accurate measurement, OK?
