So, essentially tiaras, crowns, and halos are all rather interchangeable, based on how high they are and how high the hairstyle is?

yeah basically lol. it really does depend on how it looks like on a particular hairstyle lol.

I have to keep playing with these things longer and discover all these hidden tricks.
Hmmmmm.

Oh! Has Firn ever said, do any of you know... these "named" Lost items, the ones that all share a name, like the Dagenth Hair and the Dagenth Wings share a name... anyhow. Did she create an avatar or a look called "Dagenth" and these are all pieces from it? And the same with the others? Or is there something else it is alluding to?

...i don't think so? i think its just a set name for the lost items...O:

I keep thinking we are slowly building someone's iconic wardrobe.

I mean, some of them are obviously named and labeled -Lost King's Robes mirror the look of the King's uniform. Fungus Hair mirrors Fungus' hair style

But some of the names, I don't recognize.

I thought maybe, either someone knew them and I was being slow on the uptake, or perhaps Firn had other "characters" she'd created that weren't ready to be revealed yet....

I don’t really know tbh, I just collect them hahahah. XD

I don't think we have a character called Dagenth, or Mailim for that matters. I do recognize everyone else.

And now I have looked through the Lost items I have just realized now that we have no BG lost item.

Maybe in the future?
I don't know they do seem pretty random items to me.
Do we have any hand-held item?

Yeah we don’t have characters by those names, I think its just like….a monthly set but instead they’re released as lost items lol.

I know we have a room item (the tanuki bottle) but yeah no BGs….not sure about handhelds either tbh.

Yes, it's true, the Lost items are a kind of set by themselves.
Only that you have them in different colors, not really matching one with other - until you eventually do, I suppose.
