I adore Nellie. She's the most visually appealing of all my dolls and I love her character in the books so she's definitely a winner in my book She's actually the only doll I really, really like with the Josefina mold (and the only Josefina mold I have). Her dark blue eyes (same as Kit's I think) are so pretty, the freckles are adorable, red hair is my favorite, the hairstyle is cute as heck, and to me the face mold really works for her.
Here are some pictures of my Nellie. Sorry they lack personality! I was trying to get pictures of the outfits rather than the doll herself and she's standing funny because she wanted to fall over a lot. She's strictly historical (and canon) for me, the 2 modern outfits were just because her hair is easy to deal with and the flamingo outfit's shirt is very difficult to pull on over the head. She's been wearing Rebecca's PJs for months now and I love them on her!
