Pit to pit about 21". Length from back neck, about 26". Caveat emptor: Pre-owned/vintage tees are never perfect. There might be signs of wear around collars, hems and sleeves. Might have tiny flaws, fading, etc. But I wouldn't sell them if they weren't groovy and wearable. So we're cool with that, right? That said, the graphics on this tee are in fine shape. No stains, scents, snags, or other weirdness. I thought it was Simpsons! But it's Groening's OTHER show, "Futurama." Cool! (F)
