Is the orange with gold trim version of this that's a Memorial Album reward the only +2 Alcohol Trading body clothing item available om GAMA? It says UNOBTAINABLE for the Gold Happi. I would guess then that this would make this a pretty handy item for Nanban traders that trade Wine for Saori to have then.....

Actually, I can think of three confirmed alternatives, now listed for simplicity's sake at the Alcohol Trading skill page; they don't require you to be in a Merchant class job to equip them, which the Naka-Haori does.

But that said, the Nanban Trade MA reward N-H is potentially easier to obtain, compared to the rest... and odds are you'd be in a merchant job that favored AT if you're going to be buying up alcohol for whatever reason, anyway.
