Sabyasachi Mokherjee, a sought-after Indian designer, is highly sought after.
His designs are best known for their bridal wear. They were worn by Deepika Padukone and Priyanka Chopra Jonas on their wedding day.
To reach a wider audience, he joined forces with H&M to create a more affordable collection for high-street shoppers.
"Wanderlust" was born out of excitement, but soon became a source of criticism.
A letter was sent to the designer by representatives of Indian crafts workers, expressing disappointment at the way the clothes were made with a fast fashion label.
Others couldn't buy the clothes in time to avoid being sold out. It was a business success, but Sabyasachi revealed to BBC News his motivation behind the collaboration.
