I cut a size 12 and made a few adjustments. I cut the back piece in half just below the sleeve notch. After adding seam allowance, I cut the top back bodice in main fabric, and the bottom piece in contrasting fabric. Noelle seamed on the short side so I added more length at the back (around 1.5"). I wanted the contrast piece to be slightly gathered so I added 2"to the centre back. For the front piece I created an inverted rounded hem- leaving the centre front as is but grading it out 1.5" longer at the side seam.
I sewed the sleeves a little differently than described in the Noelle Sew along post. To hem the sleeves they are simply serged / zig-zagged and then turned and stitched, before sewing the side seam. Instead, I sewed the side seam first, stopping at the sleeve notch. Then pressed the seam allowances away from the seam pressing all the way up to and around the sleeve. I then pinned and stitched 1/4" from the bottom hem up the sleeve allowance, around the sleeves and back down to the other hem. Finally, I reinforced the seam just below the sleeve.
