"I'm undercoverDoing secret work inside a company or group, not revealing who you really are. at fashion giant Boohoo," says BBC reporter Emma Lowther. "The company's built its reputation on selling cheap, on-trend clothes. It promised to change." Her conclusion? It had not.

She was filming a TV show about the company, three years on from when journalists reported that workers making clothes for Boohoo were paid as little as £3.50 an hour.

Later that year the company made a promise to pay the factories that make their clothes fairly, so that the workers at these factories can be paid fairly too.

But Emma Lowther found that Boohoo was still trying to lower prices all the time. They sometimes even gave suppliers less money than they had agreed.

Boohoo had also cut the time it allowed the suppliers to make the clothes, to as little as six weeks.

One survey found that on average fast-fashion clothes were worn only seven times. Today, we buy and throw away more clothes than before.

Yes! Fast fashion is wasteful, bad for the planet and bad for the people who have to make clothes without being paid for their time and hard work.

No! It is great that everyone can now buy clothes at cheap prices. There is nothing wrong with cheap clothes as long as workers are paid properly.
