Americans purchase an average of 64 items of clothing annually, according to the American Apparel & Footwear Association, thanks in large measure to "fast fashion" companies like H&M and Gap, which use foreign labor to produce clothing.

John Oliver explored the cost of cheap clothing on "Last Week Tonight" on Sunday. The companies that sell these clothes have for years had to apologize for working conditions and have even been accused of using child laborers. Case in point: Kathie Lee Gifford, who once testified before Congress about the need to protect labor rights internationally after it was discovered her clothing line was made by underage workers in sweatshops, was later wowed on her show by a $19 Joe Fresh blouse.

"If she can forget the human cost of shockingly cheap clothing ... it doesn't give you much hope for everyone else," Oliver said.
