Here is two versions of MIL_COS_00. One with panties instead of her leggings and another full bottomless. The Panties version will replace the leggings one and the bottomless will work as a Layer2 (press F to see it). You can use both of them. I used the Leifang naked body made by @fgh1t6 to make a pantless and a pantyless version for Mila's MIL_COS_004 (costumes 10-12). Also used @fgh1t6 Ayane's AYA_COS_002 (pretty awesome btw) for the panties. Use REDELBE to install it.
