This turtleneck top is made of cut-and-sew material, perfect for fall and winter. In winter, it's great as an inner layer for one-piece and shirts. The Tenjiku fabric is knitted with smooth rayon-blend yarn, giving it a glossy, smooth texture. A small amount of polyurethane is added to tighten the stitches, giving it a warm, firm feel. It comes in three colors: basic white and black, plus royal blue, which can be used as an accent color.
