Thank you for viewing! This is a dark navy short-sleeved round-neck undershirt from Wing. Made of a cotton blend with warming functionality, it's perfect for the coming season. It fits snugly against the body but is stretchy. The size is marked as M, but it would likely fit a size S perfectly. The second image is for comparison with black. It appears washed out, but the actual color is a much deeper shade. I wore it once, but it was too tight for me... Please feel free to ask any questions in the comments. - Color: Dark Navy - Style: Short Sleeve - Design: Round Neck Thank you for viewing!
