Got this as a gift a few years back, printed year could be wrong I honestly don't have a clue. 2019 - 2021 could all be correct, shit could even be earlier then '19. Not worn a lot since it kinda creeps up (the bottom / sleeves) and it's not too big. It is a Large but this should've never been sold as one. Medium at best, and that might even be pushing it (coming from me, a guy who can fit into Small t shirts).
Not worn a lot, and most likely obtained through EMP (don't know, again it's a gift). But this design has been out and about for like what? 15 years?
Close up picture is way too bright, keep that in mind! The unicorn is pink (ish) not white in case it wasn't clear from the pictures.
