I have all of them and the only one I regret is Bust The Dust. The dust system is so far over the top I have to shut it down. If I didn't my sims would never do anything else but vacuum.
I love: Moonlight Chic, Incheon Arrivals, Modern Menswear, Fashion Street, Industrial Loft, Throwback Fit, and Blooming Rooms
I like: Everything else.
I haven't found a lot of use for Carnaval yet, but that's only because I haven't created a sim that would be perfect for it. I have been dying to create a transgender sim or at least a non-binary or gender fluid sim, but I haven't because the options in CAS for body customization are so poor. I can't create the look I want. The fashion in that kit is awesome, I'm just looking for the right sim to wear it is all.?
