More like Adult Medium (but Im a little smaller than that so it depends on the brand either it fits perfectly or its a little too big)
But for like the last two years I was adult small and they freakin never made adult small jerseys
not only that but they throw some off brand crap at you... I went to go buy a pair of jeans there once.... after I paid I noticed the name of the Jeans was Big A. How friggin embarrassing is that.... I bought these Big A$$ Jeans at the fat store.... unbelievable.
