Very cute outfits! I just bought a doll pattern to make some matching outfits for DD10's American Girl dolls. I bought her a My Twinn doll a few years ago. Here are a couple of photos of her with her "twin" whom she named Mary Kate.
She is a cute doll, she definitely larger than the AG dolls. One cool thing is that her body is bendable. You can pose her all sorts of ways. It was fun to see her with the same little freckle under her eye that DD has. On the other hand, my DD has curly hair. If you leave it alone it dries in ringlets. I thought I picked the best hairstyle, and they had a photo of DD, but the doll came with slightly wavy hair so I ended up sending her to their doll hospital and paying for new hair, which did turn out better, but still not as cute as DD's. However it did not take long for the hair to turn to frizz. My friend's DD has a My Twinn without curly hair and it also became a frizzy nightmare. DD does not play much with her at all but I do like her for the sentimental value. However, DD has 3 AG dolls with whom she plays every day. I took her to the AG store in Chicago last year for her b-day and she took her Kirsten doll to the hair salon there because her hair was getting frizzy and out of control. She also has Samantha and Kit and their hair is gorgeous and easy to style and never gets frizzy, anyhow, the stylist there said that Kirsten and Kaya have the most difficult hair, the rest of the dolls have a different texture. We love both the MT and the AG dolls, for playing with the AG have worked out better, to treasure as a lookalike of your daughter, nothing beats the detail of the MT.
