Right, I've talked with Cybs - the other person on the custom item team - and we've come to the conclusion that we are going to be denying the item for now. The expanded story is more or less just the original with more words, we feel. A custom item needs to have specific reasons for belonging to a character beyond it being made specifically for them. In the example I gave you earlier, Tokash's mantle was symbolic of a mindset change, and a gift from a family member while representing his guild. The guild representation is arguably the smallest part of the story, making it symbolic of the character's views/personality and thus specific to them as a character.
As it stands, the story for this suit still sums up to "It was made specifically for them, and they still have it today." There isn't much of a story to work off of from there. If you have any further questions, you can DM me or Cybs. Gonna' be closing this for now.
