Bangladesh is the number two exporter of ready-made clothing in the world, surpassed only by China. For this rapidly developing economy, the garment industry is the single source of growth and the primary source of foreign exchange earnings.

Some economists have called this a social time bomb. With the impact of technology in mind, I traveled to Bangladesh to get an up-close look at the often unseen side of the fashion industry.
