It's entitled because
1) Guys should have something nice for themselves, which has been improving
2) You act as if there aren't alterative to the jacket, when there's tons of them in game THAT ARE UNISEX. Not even counting the Bestman's gear, there's the Scion jacket, the lvl 60 Shire gear, the gear from St. Mocianne/Pharos Sirius HM, gear from Holminster Switch, some of the Scavaen gear, and others throughout the game. Again, all unisex options. If you hated dresses so much, you could've considered those. But the "wahhh!! I want this one!" when there's already a plethora of alternative options seems entitled to me.
And yeah, it's not a new phenomena, but it certainly kicked up in 2019 for some reason.
