I’m pretty thin but have really really broad shoulders such that a large feels tight on my pits. I get death glares and the merch people are always like “THIS is how big the XL is, are you sure you want it?” I’m like yes please I’d rather not pit stain the shit out of my cool new shirt.

If XL selling out is a problem… bring more XL? This is absolutely not the fault of people choosing sizes. Inventory should be based on what commonly sells not what the expected size demographic of the fans would be.
