A pie crust collar is a standing neckline finish featuring a tight, structured ruffle that stands vertically around the neck. The edge is densely gathered or pleated to create a continuous wavy profile, much like crimped pastry dough. It is typically found on romantic or historicizing blouses and dresses, often extending just above a high-necked sweater or jacket.

Insider tip
To get the signature crisp fluting, this collar is usually cut on the straight grain and heavily gathered, rather than cut as a circular flounce.
