    In an era when fashion trends can change in a nanosecond(纳秒), people want to keep pace. They'll wear a look a few times and then move on to the next one. In reality, most people can't really afford this.

To meet this demand, online clothing rental services are growing in popularity. Shoppers can pay money online to rent the clothes they need, says the Fashion United website. The first company to put this idea into practice is Rent the Runway. The United States — based company has hit a $ 1 billion valuation. CEO Jennifer Hyman credits its success to the concepts of the sharing economy. She believes that the clothing rental business and the idea of dynamic ownership is a trend in the young generation. “The millennium generation(千禧一代)，the consumer, is so ready to adopt this behavior.” Hyman told CNBC.

She also points out that working women make up one of the biggest consumer groups subscribing to their services. They want more clothes but they have limited space and ability to purchase new fashion. “Rent the Runway can be a solution for them,” Hyman told CNBC, “where they can dress for the job they want and save money and time.”

Although the clothing rental business has many advantages, people still have some concerns. Journalist and author Elizabeth Cline wrote in Elle that “Renting the clothes is not as sustainable as it seems.”

Take shipping, for example, which has to go two ways if an item is rented—receiving and returning. Cline writes that consumer transportation has the second largest footprint of our collective fashion habit after manufacturing. Then there's the burden of washing, which has to happen to every item when it's returned, regardless of whether or not it was worn. For most rental services, this usually means dry—-cleaning, a high— impact and polluting process. “They can produce hazardous waste and air pollution if not handled correctly, and they're often paired with stain removers that are more toxic than the solvents themselves,” she told the Fashion Platforms website.
