Shein, the online retailer that has turbocharged the global fast-fashion industry, is planning to deepen its foothold in the U.S. as its sales to American shoppers continue to soar.

The company is planning to build three large distribution centers in the U.S. that could eventually reduce shipping times for its customers by three to four days, George Chiao, president of Shein’s U.S. operations, said in an interview. It is also planning a hiring spree in the country over the next few years, he added.
