Over the past two decades, there was a 90 percent decline in apparel manufacturing industry in the U.S., from 940,000 jobs in 1990 to 136,000 in 2015. This has been in part due to the Trans-Pacific Partnerships, which provide incentives such as lower tariffs for companies that want to produce clothes overseas - though the merits of free trade have been hotly contested in this election cycle.
