A top is an item of clothing that covers at least the chest, but which usually covers most of the upper human body between the neck and the waistline.
[1] The bottom of tops can be as short as mid-torso, or as long as mid-thigh.
Common types of tops are t-shirts, blouses and shirts.
The neckline is the highest line of the top, and may be as high as a head-covering hood, or as low as the waistline or bottom hem of the top.
Tops may have straps around the waist or neck, or over the shoulders.
