Sezon 1

Mary Portas believes this is a window of opportunity to restore some life back to British manufacturing. So she's heading to Middleton, Greater Manchester, to set up a new production line for British-made knickers.

As the apprentices set to work mastering the machines, Mary soon realises there is more to the knicker game than she originally thought, and battles to keep the retail price at the £10 she wanted.

It's all hands on deck as Mary and the factory workers prepare for the launch of Kinky Knickers at London department store Liberty. Production is now in full swing at the Middleton factory, but progress is slow, and there's a setback when the lace trim supplier goes out of business.
