RARE Iron Maiden half-shirt Purgatory Vintage!!

This is a damn near impossible to find shirt, not to mention it's an actual half-shirt, sold that way new in the store, no sleeves, half length, and I actually wore this puppy in middle school. Thank god there's no pic proof. My ex took the sides in so her boobs would look amazing in it, This is a 35 year old shirt, it's shrank, super thin soft, some holes and stains, but the holy grail nonetheless. I'd be guessing for size, xs? UPDATE THIS WAS STOLEN FROM MY HOME what a total bummer.People suck
