That style is ridiculous. Bad placement of the zipper, and if it will always break when people (naturally) try to operate it, the designer should have used a faux zipper. Why are they even selling that thing if they have to constantly tell the customers part of it is defective? Those shirts should have been bundled up and sent to a liquidator, or a textile recycling company.
Don't the QVC buyers even check the samples to see if everything works, before they place an order with the manufacturer?
