Ok thanks to OCD and the strategy Guide I have made a note of all the items used in this pic. So now you can make this party if you wanted to. The only items I made a guess on where the Lighting Conductor and Metal King Spear, they had some of the same pic in the guide, so I made them the best of what it is.

It's a reference to an item you can get that if held lets you wear most opposite gender clothing (so you can have basically anything but a male wearing clothing that shows cleavage).
