Neck circumference is measured how?

The measurement of neck circumference is determined by taking a specific distance that reflects how clothing fits around the neck area. Option A accurately describes this process, which involves measuring from the center of the top button to the farthest edge of the buttonhole. This method accounts for how a shirt or garment will close around the neck, ensuring a proper fit and comfort for the wearer.

The other options involve measurements that relate to different garment parts or other body dimensions. For instance, measuring from shoulder to cuff pertains to the length of a sleeve, while measuring from the edge of the collar to the hem involves the overall length of a garment, neither of which pertains directly to neck circumference. Lastly, the distance from one shoulder seam to another measures the width of the garment across the shoulders, which is unrelated to the circumference of the neck. Understanding neck circumference is vital for ensuring that shirts and similar clothing provide a comfortable and flattering fit.
