The US is the second largest textile exporter in the world. Sources: https://ncto.org/facts-figures/us-textile-industry/ and https://www.trade.gov/selectusa-textiles-industry It's true that a significant amount of that is fabric and fibers, and most of the clothes sold in the US are not actually sewed here. But on the other hand, US companies also show up in other places in the clothing supply chain as well - American fashion design and marketing contribute a lot of the final value of many clothing items sold here and overseas.
