The items are not original though - they're the same items that were included with the '7/11' maid/butler costume promotion that had a convoluted way of gaining in the UK. So I guess this probably is to test an alternative to getting the maid/butler costume for UK players, given how problematic that event was handled (maybe if this is successful the maid/butler attire will also be given a similar promotion). But that's just my own idea so take from that what you will.
