“Today, Spring/Summer collections are debuted on the catwalk in September and October and delivered to stores between January and March while the Autumn/Winter collections are debuted in February and March and delivered between July and September. In between, seasons known as Resort and Pre-fall are designed to come to shops in midwinter and midsummer, respectively. … It’s no surprise that spring merchandise is less appealing to customers facing widespread winter storms, and that warmer weather is knocking the demand for autumnal clothes. …

“We have to accept that not only is the fashion industry being affected by climate change, it is also a contributor to a multitude of sustainability issues. The seasonal calendar promotes a relentless drive for speed, waste, and overconsumption, which now characterizes the entire industry. …

“We need to slow down the pace of fashion. … We no longer need to produce the unwanted and we certainly no longer need to consume at our current rate. If designers and retailers take the lead to improve production habits, consumers will hopefully follow suit. Let’s not abandon the fashion calendar; let’s recreate it, together.”

—New York designer Carrie Parry, writing in the Guardian at the close of Spring/Summer 2015 London Fashion Week.
