Way back when, when I first started out on this site (6yrs ago), there was a trench coat. Now, this trench coat was extremely special, as it was Nathaniel's trench coat. I remember this item. It was there. I had it. I want it back. Unfortunately, I can't, for the life of me, find it, or remember its name. Urgh.
Does anyone know what this clothing item was called?

?
Nathaniel looks sorta Montre-y. Maybe something like that?
There used to be some winged trenchcoats, including a Montre one. This is probably what you're thinking of?
They don't exist any more. They had a major revamp almost a year ago. Here.
Well SHOOT. I really wanted it back. Wait, then what about the people who already had it in their wardrobe? Did it just disappear? It's kind of odd that Subeta just up and got rid of an item.

If you already had it in your wardrobe it should be replaced with the revamped version. You won't have lost the item. It just won't be the Montre one any more.
