I decided to go ahead and make the costume, whether I wear it a Comic Con is another matter. I didn't want to use Lycra and have it look like a bodysuit, so I went with a twill type fabric with some stretch. It's much thicker than Lycra so it will have some structure and will be able to hold my fat in.
This top was definitely a pain in the butt to make. I had to adjust and re-adjust over 30 times. I nearly gave up.
I started with the Kwik Sew pattern 2943.
This was definitely the wrong pattern to use. The sleeveless turtleneck is very boxy and very loose. Even when I used the S size (and I'm usually closer to a L in everday tops) it was HUGE and very non flattering. I had to add darts, reshape the waist, take in the shoulders, reshape the turtleneck and change the shape of the armholes. What a PAIN!!
After 3 days I'm finally done and quite happy with the final product.
The 2nd version is definitely much better than my first one.
