You may be wondering, who decided the first Monday of September was the official last day to don white? A quick Google search proves historians aren’t quite sure. A couple sources blame it on the upper class of the mid- to twentieth century who wore white to signify wealth and status in the summer. Other sources say it’s simply because white doesn’t absorb the sun’s rays, and because Labor Day marks the end of summer fun, it makes sense to stop wearing the heat-banishing hue. Whatever the source, as women of the twenty-first century, it’s high time to break this silly fashion rule and wear white all year long. Besides, you can’t put an expiration date on style—as these women prove.
