Chie's Fighter Armour from P4G.

Default appearance:

p4-fighter, bikini armor, leotard, black bandeau bikini top, bikini top only, detached sleeves, white sleeves, gray short shorts, choker, navel, fingerless gloves, knee pads,

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

red leotard

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. Especially the leotard be finnicky, usually addinga bit of weight helps (leotard:1.1)
