Vintage purple/blue/tan CAT brand flannel shirt small

This shirt is so soft because it’s so old! The tag has washed away any info, but the measurements- & based off my size, it’s for sure a small. The pictures show any flaws; which the paint on the bottom front is the only one. I think it adds to the patina.. or retro-ness of the shirt! (Is that a word?) also cute CAT patch on on of the pockets.. Measures Arm pit to pit: 21 Inches Shoulder to the bottom; 26 inches Arm pit to the bottom: 14 inches
