Scoop neck

A scoop neck shirt is one in which the scoop-shape neckline drops significantly below normal limits. Some scoop neck shirts, when worn by women, are cut low enough to display significant amounts of cleavage. These shirts come in a variety of forms, including those with and without buttons. At least one fashion designer has recently produced a line of shirts for men that can be converted to scoop neck shirts by clipping a thread in the collar. The scoop neck shirt is often worn as sports or casual wear by women, and has grown increasingly fashionable for men.
The exact shape of the neckline may vary from a slightly exaggerated circle to extremely severe parabolae, with limitless variation between.
