These changes are currently unavailable; all appearance changes are more or less secret, intended to be unlocked through two separate events. Appearance changes such as hair color, tattoos, eye color, horns, and piercings will gradually appear in the game as new events are added.
Technically, they're already implemented; all that remains is to wait for the corresponding event to appear.

You can earn money by:
1. Working in the tavern
2. Working in the park
3. Digging for pearls in the slums (coastal slums) and selling them at the pawn shop (dirty slums)
4. Working on the farm
In the next expansion, you'll also be able to work in the laboratory located in the same location as the hospital.
I'll probably add a tip on making money to the flophouse location.
