a rare starlight?

Apparently in the mabi forums, there was this guy who has a Starlight that he received from his friend and basically everything on the robe is flashy. As I said apparently pretty much the whole robe is flashy. Part A and Part B of the robe is a black flashy while the inner robe is red flashy. According to this one guy, "It's... the legendary ultra-rare starlight robe!" with this hilarious reaction face and it was from the exploration treasure event in 2009. Did anybody else heard of such robe?

Did such "legendary ultra-rare" starlight robe ever existed in that event?

Not to the best of my knowledge. Believe it was just dyed that.
