/cgl/ - Cosplay & EGL

So I'm thinking of selling these, I just don't know what they are worth!

1. Ista Mori Nameless Poem in L, never worn, still has tags but it's the first release. The collar & cuffs are not a true white but a ivory.
Is this OP still popular?

2. AP coat of arms tartan OP in red.
Worn by previous owner, has very slight pilling.
I'm guessing not worth retail since it's not popular? I was thinking around 150 euro's?

3. Infanta green military jsk & cape XL (runs small).
Still has tags, never got around to wearing it desu and I don't think I ever will so this beautiful piece needs a new home.

4. JetJ robe l'agneau size 1.
Worn once by previous owner, still in like new condition.
Not sure I want this gone yet but curious about the price it may fetch.
