Outfit not active despite all pages used

Scaletho · January 24

This Tel Var Merchant confirm that outfit is "already activated" but in fact no piece is really confirmed in my menu. I need help, please.

Do you have the pages somewhere? Are you eligible to buy them?

The error does not say you know it. The error says one of three things is happening: you know it, you have “an item that can bestow it” (meaning you have the page but have not yet consumed it), or you’re not yet rank 20. Since both your collections and the item tooltips say you don’t know it, I’d suggest looking at the other two possibilities.
