12. Why are there only two main seasons in fashion?

The process to design, produce, and present a collection has typically taken about six months, therefore the fall/spring breakdown not only makes sense weather-wise, but also allows for the appropriate time for designers to complete their work. However, as the the fashion industry has been able to gain speed in the design -and-distribution process, new collections have been able to emerge (and be sold!) more frequently. Hello, pre-fall and resort.
