Loro Piana has been spinning wool from cashmere goats, merino sheep and Andean vicuna for generations. Today it produces some of the world's most expensive clothing and accessories.  Since 2013, it's been part of LVMH, the French luxury conglomerate, which has pledged to preserve the Italian company's reputation for the highest quality.
