The product page for this item says that the lounge pants have a drawstring waist.
For people who are tall and slim like myself this seems ideal. But they don't have a real drawstring at all. It's a a fake one; just a bit of ribbon adhered to the front and tied in a bow for aesthetic purposes.
A real drawstring draws in, and to do so it has to have the string threaded all the way around the waist. That is not the case with these lounge pants.
I'll be returning them and expecting a full refund (including postage), as the info on the products page was false at the time of ordering.
