Simplicity 2634 (modified)
This is Simplicity 2634 view A with some changes.
I eliminated the tie and tab front. I eliminated the pleating on the bottom half, eliminated a center front seam, and took out a few inches from the bottom width (to make up for the lack of pleating). I also cut the bodices on the bias to play with the stripes.
The stripes are much more subtle without a flash.
The fabric is a linen blend I bought at Joann's in fall 2010, I think.
