Sense: A Cyberpunk Ghost Story - Costume Unlocks

Here is a video showing how to unlock some of the more difficult costumes, most of these can only be done on NG+ or beyond. I don't show how to get Augments, and I did not realize when I got Kunoichi, but I mention them here.

Augments: Talk to the woman by the bathroom at the bar twice (NG+)
Net Diver Mei: Unlocked in NG+
Qi Pao: Find all of the documents/journals in a playthrough
Ushi: Get the Milk Tea out of the vending machine when you get the choice (NG+)
Kunoichi: Retrieve the kunai from the stylist's room
Bikini: Get the key from the entrance and bring it to the escort's room, unlock her closet
Jiang-shi: Re-seal the vampire (NG+)
Dudou: Examine the items in the final boss room based off the Yotsuya Kaidan myth (casings, lion, mahjong table, raffle spinner, wedding gift)

Quite a few of these are able to be missed, so just be on the lookout for them as you play.
