I had this outfit in my game and has now disappeared from my game. I am assuming it is store outfit but I might be wrong. sorry for the odd pic this was the best shot of the outfit.
I'm going to page @CravenLestat to take a look as he knows what outfits are store or EP/SP outfits. Did you do unlockoutfits on/off to see if it's one that's hidden?
