stringer
A men's tank top intended to show off muscles. These shirts often have a deeper neckline and a thinner chest, emphasizing the back, trapezius, and pectoral muscles in the process.
Unlike the spaghetti straps on camisoles, the straps of a stringer resemble those of a well-worn tank top, where thicker staps would be stretched-out after a long period of use and muscle gain. This look can also be achieved through cutting a shirt's sleeves or arm holes to "string" size.
