Hawkwind band yellow t-shirt men’s size small

Preowned in good condition, Hawkwind Warrior on the Edge of Time yellow t-shirt, it’s labeled a medium but it’s measuring as a small, and my husband didn’t wear it because it was too small (he’s a medium). Some overall wash wear but the design is crisp and the fabric is in great shape, no stains, holes, etc. 100% cotton MSRP $25 Measurements: Pit to pit: 18” Overall length: 26”
