To add to the “princess” look of this dress I wanted to do paned sleeves– you may know them as “Snow White sleeves”– where a contrasting-colored lining peeks through slashes in the outer sleeve. However, since I didn’t want to make two separate layers I decided to simply insert strips of white satin into the main purple sleeve, pleating the purple fabric so it looked like the white was a separate inner sleeve. For the technique I relied heavily on this tutorial, which is awesome.
For my basic sleeve pattern I wasn’t confident enough to draft my own– I really didn’t feel like measuring and guessing about the best curved shape, so I raided the $1 pattern bin at my local store and picked out a girls’ pattern that had puffed sleeves to use. I cut the sleeves out, then cut each one into four pieces and inserted 2.5″ wide strips of white satin between them, ironing the 1/4″ seam allowances towards the purple fabric .
