Concept designs are concepts for a reason. Doesn't mean it is always going to be the finished product. I like both tunics. Though I don't see the reason to change this now. It is not really a bug more like a change in design. I don't remember when Yoshi showed the picture for the tunic. However, it could of been drawn as an idea in game. But was already changed. But who knows, besides the dev team.
Now here is another thing they could do, which they have done several times in the past. Make it as a new crafted and dyeble gear piece. If people are so bent on the color schemes. They can use that.
