I really hope that the current butterfly SSR in VV comes to Scarlet. It's REALLY pretty (and I was lucky enough to get it for both Marie and Ayane). I'd love to see it in different colors.
If Peace goes through, Sandwich should also be safe. Caviar's undersuit is actually similar to Pistachio (the bottoms are way skimpier on Pistachio, though), so I feel like it will probably go through on PS4, but there's a chance that the netting dress may be a factor in allowing Caviar through. Norimaki and Illusion are bandeau tops, so they should be safe, too. Honestly though, some of the cheap suits coming up are my absolute faves of all the original DLC, so I can't wait for suits like Macchiato or Decuple.
