What are the non-retired Subeautique sets? Some of them on SubetaLodge aren't updated, and I really want to plan ahead on what to buy from the shop. Thanks.

Subetalodge is usually pretty up on that sort of thing. Maybe you should email them?
I know that the more fashionable on the Human Avatar forum would be more likely to know the answer to this. I am thinking that Argo Orange and Giselle Frog are the oldest, followed by Court Jester Hazel Toffee and all the sets released for the Masquerade this year.
