Very cool boxy blue vintage tee with green elephant patch on left breast. Late 70s/early 80s would be my guess. Color is truest in hanging pics. No material or size tag, but I’m almost certain it’s a cotton/poly blend and fits me well as a small/medium—see pics for measurements. Some general wash wear/light pilling and the inner collar has come unstitched a bit where the tag was, but overall in very good vintage condition. Sleeves are stitched into place folded, and might benefit from some reinforcement eventually, or could be snipped and let down easily if preferred. Feel free to reach out on IG @marmosetz🐘💕
