I recently bought a Black One-Piece Swimsuit (though apparently I now own 2 of them). It shows up in my Closet, but not in my Wardrobe when I go to put it on. I noticed that it also doesn't show up in the Dream Builder, even though the same item in different colours (blue for example) does show up. I was wondering if this was just an issue that I was experiencing or if it was an issue with the Black One-Piece Swimsuit in general? Thanks!

I don't think this is a glitch it is likely that the item's art for when it is on our HAs has not been uploaded and added to the code. The dream builder shows all clothing items currently coded with art for HAs.
