Turtleneck Undershirt
Color: Black, White, Apricot, Size: Small
This shirt can be worn as an outer shirt, but the fabric and the feel are completely that of an undershirt. This is good for layering or to keep my neck warm in the cool/cold months.The shirt is lightweight and very basic in style. The stitching had some loose thread spots, but nothing major. The colors and finish of the fabric is muted/drab.
