I have never purchased clothes for my American Girl Just Like You Doll, except for a pair of white ice skates. I make all the clothes myself! I have done a ton of research searching for free patterns, and have had some success.
I found this pattern on SewAdollable.com. This is the link to the pattern and instructions: One Shoulder Dress Tutorial. The skirt turned out a little shorter than I had expected, but now she could wear it with white tights and go ice skating in the winter!
Next is a purple and black skirt outfit!
Comment if you decide to make this, or Like if you like my version of the dress!
