Naoto's Coronet Armour from P4G.

Default appearance:

p4-coronet, bikini armor, detached sleeves, panties, garter straps, midriff, crop top, bare shoulders, frills, center frills, navel, ascot, brooch, thighhighs

You can change the color somewhat consistently by editing the 'bikini armor' tag:

red bikini armor

This lora was trained on screencaps I took from P4 Dancing All Night. It's not super duper consistent so I might tweak my training settings if I ever make a V2.
