What does no white after Labor Day mean?

“No white after Labor Day” is an outdated, North American fashion rule about when to wear white clothing. The “rule” was to avoid white clothing (particularly white dresses, shorts, or pants) before Easter or after Labor Day.

In the US, Labor Day marks the end of summer vacation season and the onset of cooler temperatures. White and pastel colors are popular in the summer because they help people stay cooler. Dark colors attract more heat. Most people don’t really consider wearing white after Labor Day a faux pas anymore, though.
