Creating Sims 4 CC tattoos

I am trying to recreate Jane Doe's full body tattoos from the show Blindspot (10/10 would recommend BTW). For her neck tattoo I am not sure where to place it on the female template to make it where is should be in-game. If someone could please help me out that would be great. Thanks!

PS I would add photos, but the "insert image" option isn't working.
