a selection from this excellent post by u/send-me-a-puffalope, comparing F1nn's looks over time
the most recent photos in this set are the black and tan color block top and cat ears+choker+strappy black dress (far right pic in the first set), which are both from the 12/21/22 stream, and the oldest is the far left pic from the first set, which I think was taken in front of another streamer's setup; for other carbon dating purposes, F1nn started streaming in his own first house 7/31/20 (afaik), which is the one with the blue wall panels and no bed in the background
