"Basically, in life, rule of thumb: if you don't absolutely have to clean anything, don't clean it."
Fashion designer Stella McCartney said this in an interview with the Observer this weekend, adding that she picked up the tip while working for bespoke tailors on London's prestigious Savile Row. Instead, she says, the "rule" is to "let the dirt dry and you brush it off".
bespoke[bɪ'spok]: adj. 定做的，定制的
It may have been a throwaway comment at the end of the interview, but something about this line stuck with readers - many of whom have been doing several loads of laundry a week.
So does she have a point? Is it better to avoid washing your clothes?
Killing the planet one microfibre at a time
This isn't the first time McCartney has recommended not washing our clothes. In fact, she has long advocated avoiding the washing machine - both for the longevity of the garments, but also because of the impact washing them has on the environment.
Laura Diáz Sánchez, from the Plastic Soup Foundation advocacy group, agrees with this, particularly when it comes to high-street clothes, which contain more synthetic materials such as polyester and acrylic.
"Every time we wash our clothes an average of nine million [plastic] microfibres are released into the environment," she tells BBC News. "The way we wash our clothes affects this, as well as the way our clothes are made - but the more we wash our clothes, the more microfibres are released."
When you do wash, she recommends setting the machine to a lower temperature and using liquid detergent: "Powder detergent creates more friction between the clothes [during washing], so more fibres are released, whereas liquid is smoother. The less friction there is in general, the fewer fibres are released."
