The "medal" symbol for the costumes look like the one used for "upgraded NP" and "upgraded skills". If that's the case, then we might get them through "Costume quests" or Interludes specifically made for, in the future. We might even get some for the Anniversary campaigns.

Let's hope I am right! Regardless, it won't be a gacha thing, and I'm extremely glad for that.
