Step 1 : Introduction to the question "According to an age-old fashion rule, Labor Day is the last day you can wear what?"
Wearing white after Labor Day has been a no-no in the fashion world for decades, but if asked why, many people wouldn't know the reason behind the strange end-of-summer rule. There is no single explanation for the rule, but there are several possibilities regarding its origin. One common explanation is practical.
