There are two dolls of Damon. One is from 1864, and one is from the present day. For the 1864 version, Damon had blue/gray jacket, and for present day, he had a leather jacket on.
For Stefan's doll, there is no 1864 version. Just present day version. He also wears a leather jacket but with a blue/gray top underneath
Katherine's doll only has an 1864 version. She is wearing a elegant green dress with some-what matching accesories. Her hair is in an up-do with 4 curls coming down.
Elena's doll is more how she looked in season 1. She is wearing a brown jacket with a red shirt and denim jeans. Since Elena was born in the 21st century, there is no 1864 version.
