LONDON, April 30 ― Online fast-fashion retailer Shein is courting brands like toothpaste conglomerate Colgate-Palmolive and toymaker Hasbro as it tries to sell more household names on its platform.

Known for cheap own-brand clothing and accessories, Shein is moving into other categories and has given brands and retailers access to its platform in nine European countries so far, having done so in the United States, Brazil, and Mexico last year.
