Just as gingham is a quintessential summer pattern, plaid is all about fall. Historically plaid has been a checkered or tartan twilled cloth, typically made of wool. The Scottish word “plaide” dates from the 16th century. Think kilts (Outlander!), scarves and windblown moors. And yes, school uniforms! Maybe that’s why I loved this classic pattern even as a high schooler? This fall, plaid is making a serious style statement in unexpected color combinations and silhouettes. And I for one couldn’t be happier.
