You can wear white after Labor Day; the old fashion rule that you cannot wear white after this holiday is considered outdated. The tradition originated in the late 1800s among the American elite as a seasonal indicator tied to practicality and social status. However, today it is widely accepted to wear white year-round. To make white clothing feel seasonally appropriate in fall and winter, choosing heavier fabrics like wool or cashmere and pairing white pieces with autumnal colors works well. Ultimately, fashion is personal, and wearing white whenever you want is fine as long as it suits your style and comfort.
