Simplicity 2813 (Snow and Cinderella) would work for the sleeves, cape, collar, and headband. Simplicity 2354
would work for the dress, although you might want to round the neckline a smidge. The pattern has bust measurements of 40 to 54 inches (sizes 18W-32W).
I'm finally doing a Disney related costume!!!!! I've wanted to participate in this thread for who-knows-how-long. I'm making an Evil Queen costume to match my best friend's Snow White for Halloween, and will maybe post progress pics as I work on it.
Just wanted to tell you ladies, and occasional gents, that I admire your work so very much. I can only aspire to sew and craft so well!
@LKD: Periwinkle*ahhhhhhhhh! Great job!
