The yoke is the piece, or pieces, of fabric on a dress shirt that drapes across the shoulder and back. This important piece provides shape for the rest of the garment and enables the wearer to move their arms comfortably. A yoke can be one piece, or “split” into two pieces.
Zip collars are a staple for sporty and casual sweaters to give you a modicum of extra warmth when you need it and ventilation when you don’t. A zip-collared sweatshirt or knit is a useful layering piece for transitional weather in spring and fall.
