I'm missing things from my wardrobe. I know I had a Magical Fairy Crown in there for sure, looked at the "crown" achievement and notice some that I had in the wardrobe were not coming up as being checked off. There's other items too but since my wardrobe was so big (10 years worth of adding stuff) I can't pinpoint a lot of it. So is it just a lost cause and I have to re-purchase whatever just isn't there?

Any help would be great. Thank you!

I have the same problem. New items don't show up in V3 wardrobe. They show up in the old one. When you add them there, you can edit them later.
