White clothes can work after Labor Day and at all times of the year.
As Louis Anderson shows us, it's a myth that white should not be worn after Labor Day. It's a year-round color that doesn't have to be relegated to the back of the closet after early September. We've recently seen A$AP Rocky, Pusha-T, and other style icons do a full head-to-toe look on the lighter side of the color spectrum, and there's no reason why you can't, either. Just try not to wear a bowtie with it.
