This dress and hat is based on a pattern I made for Barbie (available as a free download on Ravelry) in 2 different colourways
The dress is a simple feather and fan stitch at the hem and garter stitch for the bodice. Using garter stitch means there is no need to knit fussy neck and arm edges. The dress was fairly simple to design but the hat was a bit tricky. As you know Teddy Bear heads are an unusual shape so its not easy to design a hat that actually stays in place. I tried sewing on elastic hair bands, making holes for the ears (not a good look for a witches hat!) Then came up with this pattern which stays in place if slightly askew or can be pulled down over the ears.
