A tunic I made for an 18" doll (American-Girl sized) based on the character of Amelia from the anime Slayers (or a younger version, at least). The shirt was made using The Doll's Dressmaker (by Venus Dodge) patterns and the tutorial at The Bean Stalk.
I used bias tape for the trim, and purchased trim around the yoke. The shirt seals by velcro in the back, and has hook-and-eyes on the sleeves to give them enough give to get hands through them. Not the best job I did on sewing -- you can see a lot of threads on the sleeve closures.
I tied the shirt at the waist with a sash, but plan on making a belt. One of these days. It has the problem of any high-waisted thing on a female body, the effect of making you look pregnant or five years old.

Not the look I was going for, there.
Three lessons learned:
There's some loose threads, but not a bad project. The folks at the AG>18 community on LJ liked it.
