Can't find costumes in dressing room

  • Hi, I just came back from inactivity and I wanted to preview some cute costumes in the dressing room and when I tried searching for some items, they don't exist. For example, I have a elin devil-striped swimsuit and when I manually searched through the dressing room, it's not there. I also noticed that there were same outfits with different costume names such as Elin Black Cat Club Costume vs Black Paw Outfit (Elin). Is it possible to obtain some of these old costumes via shop(like does the shop do some sort of rotation with lootboxes/costumes)? And finally, is there some sort of a list that showed what costume names have changed?
