I'm curious about how people get twin dolls. I know someone likes to get exactly the same ones. There are also people buy difference dolls from same company and put similar face up...or it can be one doll in different colors of skin? Now I'm planning about having a couple of Luts Avalanche in the future, but can't decide to buy two normal versions or one normal&one sleeping. If anyone has experience about it that will be super helpful! I'd love to know how everyone prefer.
