This is Kanani, the American Girl doll of the year. She is from Hawaii, obviously. When I spotted some Hawaiian-print fabric I knew I wanted to recreate her outfit for my niece's doll.
The skirt pattern I used had two layers, but I added the ruffle around the waist. The tube top was super easy. I got the pattern from Liberty Jane Patterns. They have lots of cute, cheap, modern patterns that I haven't seen anywhere else. I have bought quite a few and can't wait to make more of them. I like that this top can be worn with other things that match.
Here are all the leis I made to go with it. I got three leis at Hobby Lobby for $3, and I only needed one for the doll. I restrung it to fit her head, around her neck, and around her ankles.
