Simplicity Pattern 2601 and am obviously still not used to the sizing differences-again I was cautious and cut the fabric much bigger than I needed, especially for the back piece. It was too big around the waist but I was able to put in a couple of darts in the back and it looks just fine and fits well.
This was also my first use of French seams. The fabric definitely needed them as it frayed very easily and was sheer enough that you could see through to the seams. I used this tutorial from Freshly Picked to get started and once I had done the first few it got pretty easy (although when attaching the lower sections of the shirt I had to repin a few times before it lined up correctly). I really like the look of the French seams and am going to try to use them from now on--the extra ironing is a pain but in the end the inside of the piece looks so much better!
