It was a song about thrifting. A song against fast fashion, consumerism, and satirizing displays of wealth. That's what it was popularizing. It was a line about making the most out of the lot we're given. It was not a song glorifying the wearing of fur. Fur is poetic shorthand for wealth. You can't excise a single word or line from a song or poem from it's context. And if you'd actually listened to the song or watched the video, it'd have been pretty clear that no one wearing gator boots or or mink was cool. It was satire. The line about mink even says that it smells like piss.
