I got Lydia on December 29 to be my 1770s girl. I love how she has pincurls and a center part. She's perfect for the time period. I noticed that her body is really squishy, like a PM doll, which I like. She's not as wide as them, but as soft as them.
I also have Mia, who also has hazel eyes, and I noticed that Lydia's eyes are darker, and they look really dark and almost brown in some pictures.
Their hair colors are also pretty similar, but you can tell Mia's is more red and Lydia's is more blond. Sorry for the weird lighting on this one, but you can kind of see.
My dolls: Kaya, Josefina, Marie-Grace, Samantha, Molly, Mia, Eleanor "Ella" (1), Angelique (11), Francesca (15), Lydia (21), Charlotte (23), and Cathleen (33).
