This is already available ingame via outfit vendors. (I have two)

I thought only Urban Legend was exclusive, but had no idea the other two are as well. I wish the reasoning behind limited/exclusive costumes would change. I want to spend money on those costumes and just can't.

My picks would be: Beat Cop, Strictly Business, Urban Legend (the weapon skin specifically)

Thanks for this question. For me, the number #1 issue with Trove is that buying expansion slots does not persist between "seasons". So if I buy all expansion slots during a season, they're gone the next time Trove comes around. IMO, expansion slots should be permanent once you buy them on a character.
