NWOT U.S. Polo Assn. 100% cotton black polo M XS S

NWOT U.S. Polo Assn. black short sleeve polo. 100% cotton. Large white polo horse logo on front left breast. Size M but runs very small, fits more like an XS or S, so I included all three sizes in GM headline. I am usually an XS or S and this is a little tight on me.
