I included a suit of it as a joke in the current campaigns opening adventure.
The PCs started out attending an all night carnival type party. One of the 60+ minis I had painted up for it was a chain mail bikini wearing female barbarian/fighter type I've had for years. I called her Dejah. Some of the players got it, some had no idea who Dejah Thoris is.
Anyways, every NPC at the party had several items of clothing/loot/misc (a few even had "plot devices") that the players could acquire - by interaction or randomly.
All together there were about 500 random items. Each represented as a single copy of a card. And it makes no difference to me what actually gets acquired.
So of course out of this giant stack of item cards the Chain Mail Bikini was one of the 20-some drawn.
The characters woke up the next morning hung over, lost in the woods, missing random things they'd started with, and in possession of random things.
The 1/2elf cleric (male)? Well, the cards revealed said that he woke up missing all of his clothing save his boots & wearing just the golden chain mail bikini.
He opted not to keep/use it. He traded it to another party member for a spare wizards robe.
This particular CMB has the following properties:
*Grants the wearer the Barbarians Unarmored Defense feature, keying off of Dex + Cha
*Operates as a Ring of Warmth
*Magically sizes to fit.
*Magically always stays "just in place"
*Will not function with other armor except shields.
*Will only function when worn "Properly" I.E. openly & visibly. Cloaks/capes may be worn, but only for cosmetic coolness factors.
**Flavor text from card:
"Is it functional? Is it magical? It's definitely inappropriate...."
"You've got to be comfortable in your own skin to wear this stuff effectively."
