Need Help Finding a tattoo

[ilbeguy119]

I need help finding a tattoo, I know it's from Slave Doll interaction 

I want to get the chain tattoo that goes up the back

I'm not sure how I got it, all other dolls i tried to make didnt have the chain tattoo 

can someone help me with it

The doll's "class" determines what the tattoo looks like.  Low class will just be the seal, high class will be the full chain up the back and around the neck.  I don't know what it looks like for mid class, never had one.

Class is determined by their net worth before becoming a slave.  So, you could cheat them money before evicting them to make them available on the market.
