Men's threads turn heads

Over the past nine months, Wan Li has spent at least 20,000 yuan ($3,200) on new threads. He got some gray and blue suits, pink and purple shirts, pocket squares, as well as brown leather shoes.

In an office where business casual is the dress code, Wan says that his new wardrobe has drawn "wows" from his fellow lawyers. His girlfriend, who for three years had been badgering him about dressing smarter, should be delighted.

So what brought about the fashion upgrade?
