Cher Chui, the first customer of the retail shop, purchased knitwear costing more than HK$600 ($77).

Gloria Yao, the project development director of HKRITA, says that the selling price of recycled garments will come down once people accept the technology.

The H&M Foundation is projected to invest 5.8 million euros ($6.7 million) with HKRITA over four years.

The investment is made possible through the surplus from the H&M group's in-store garment collecting programs, which is donated to the H&M Foundation.

The H&M Foundation allocates 50 percent of the total surplus to research on textile recycling and the other 50 percent to projects focusing on equality and inclusion of marginalized groups.
