We need an "appearance store" or whatever clever name they give it, to prompt the change the hair and makeup at the very least.
Then maybe "advanced" plastic surgery to readjust the face, as V once said to something an NPC, "looks can be deceiving, this pretty face could be an implant"
Colors could be something we buy and can equip later, hair/nails/makeup.
Easy workaround
Loading up the built in character creation screen with limited options per scenario
Mirror: change nails/makeup/hair(& pubes)
Ripper Doc: pay $20-100k to modify sex/voice/face
