Wang Mingming might have nodded in agreement had she been present. In 2009, the resident of Ningbo, Zhejiang province, pared down her wardrobe to seven sets per season after the death of a friend's father made her realize possessions are temporary. She says she became tired of pouring time, energy and money into staying trendy.

"I wanted to see if I could have the same, good quality life while owning fewer things," says Wang, a customer service representative at a marketing firm.

She picks out her seven sets among old clothes at the beginning of each season, sometimes introducing two to three new items. Wang says she makes sure she does not wear the same outfit within the same week, and uses shoes and bags for accent.

The 30-year-old admits that seeing clothing ads sometimes makes her long for new attires, but she doesn't regret the path she has chosen. It gives her more time for her other interests, she says, like doing yoga every evening after work, reading about astrology and getting facials on weekends.

In the world's most populous nation, young, middle-class urban women like Sun and Wang, who have voluntarily gone on a clothing diet, are rare. China only discovered modern fashion in the 1980s, following domestic economic reforms, so the ongoing trend is to shop more - not less.

"I don't think the Chinese market is ready for a capsule collection based on the idea of streamlining one's wardrobe or simplifying life," says Yi Guo, a Shanghai-based stylist and former style editor of Vogue China. "The market is still learning and enjoying playing with Western fashion, as well as their own."

The capsule wardrobe - a collection of a few essential pieces that can be mixed and matched, worn from day to night and updated using key items - was popularized by American designer Donna Karan. Her capsule collection, which debuted in 1985, was comprised of a bodysuit, skirt, blouse, coat, leggings, jacket and dress. It was called "7 Easy Pieces".

This has since been seen as a sensible way for women, especially working women, to organize their wardrobe, allowing them to go from work to socializing by merely adding accessories, says Willie Walters, course director of BA Fashion at London's Central Saint Martins College of Arts and Design.

It's also a more eco-friendly and less time-consuming way of staying fashionable, says Jacqueline Rezak, a Los Angeles-based celebrity stylist and owner of the online boutique Rad+Refined. For example, a solid black blazer, she says, can be worn three days of the week just by changing the top under the blazer.

Since capsule pieces never go out of style, this wardrobe can be quite economical. On the heels of the 2008 global financial crisis in Europe and the United States, consumers have adopted "apparel diets", in which they do not buy new clothes for a year, says Lorna Hall of fashion trend analysis and research service WGSN.

"For some, the trigger for this was simply the need to pull back discretional spending in difficult times," says Hall, the group's head of retail and strategy. "For others, it was a backlash reaction to rampant consumerism and a credit-fuelled boom, together with the growing realization that for an increasingly environmentally aware consumer, fast, throw-away fashion was inconsistent with a more sustainable lifestyle."

In the United Kingdom, for instance, the average household owns 4,000 pounds (39,500 yuan) worth of clothes, yet 30 percent of clothing in the average wardrobe has not been worn for at least a year, according to WRAP, a British organization that promotes recycling.

An extreme form of capsule dressing, practiced by some bloggers, Hall says, is to wear the same piece of clothing every day for a year. Although their move is a reaction to the exhausting, mind-boggling array of clothing choices, the bloggers make their point for simplicity while remaining trendy with the help of accessories.

Sun Yumiao and Wang Mingming might not have shrunk their wardrobes that much, but they know by now that looking good does not mean owning and spending more.
