John Oliver's quest to right every wrong in the world turned its face toward the "fast fashion" industry on Sunday.

Fast fashion brands, specifically H&M, Walmart, Gap, Joe Fresh and the Children's Place notoriously take part in unethical business practices in order to keep costs down. These companies have been called out on their practices multiple times and while they claim to have changed policies and improved work conditions, it doesn't seem like that actually happened.

John Oliver put these companies— and Kathy Gifford— on blast this past Sunday night during Last Week Tonight.
