After trying on muslin #2 I had the following concerns - the dart had been dropped too low, the front neckline still felt a bit big, and there seemed to be too much extra length in the shoulder area. I also had figure out what skirt length to use.
In the end I made a ton of bodice muslins and quit at the point were my patience ran out. You'll only see the final muslin since people under deadlines can't wait to favorable photo days. (There wasn't much difference between them anyway.)
Break down of all the final fitting adjustments.
1. Raised the bust dart 1/2".
I'd previously dropped it 1.5 inches from the original position, so final dart location is 1" lower than the original.
2. Put a 3/4" hollow chest adjustment in front neckline.
In muslin #2 I felt neckline was still exposing a lot of my shoulder. I'd picked a dress with sleeves so that I didn't have to mess around with special undergarments, but the neckline was exposing the whole bra strap. Adding a hollow chest adjustment helped bring the neckline closer into the neck, giving me more bra coverage. I didn't need to adjust the back neckline in anyway, probably because my forward shoulders need extra length in that area.
3. Removed 3/8" of grading in the shoulder area only. This change was made to both the front and back bodice.
McCall's 9572 has an elbow dart and it wasn't in the correct position. With the added grading the shoulder area felt a bit too big, even though the waist was perfect. This makes sense because my shoulder/bust area is a size smaller than my waist/hip area. Lucky for me a solution wasn't hard to figure out.
I'd put one of the grading lines right next to the side seam and decided it to use the underarm notch as a separation point. I cut the notch deeper so that it connected with the grading line, breaking it into two parts. Then I removed 3/8" by moving upper part of the graded area back together. This operation left a small bump out under the notch area. To "true" the area I redrew the underarm curve. Here's a picture of that adjustment before add the sloping shoulder adjustment mentioned in step 5.
4. Raised the kimono sleeve curve 1/2".
The ease in the upper part of the kimono sleeve was a bit too much for my modern tastes. I decided to reduce that area by raising the curve of the kimono sleeve and narrowing the upper part of the arm. To do this I redrew the curve 1/2" higher than the original position and blended the underarm seam into the elbow area. (Didn't take a picture of this before cutting off the excess. Oops.)
5. Made a 1/2" sloping shoulder adjustment to sleeves.
After mocking up some of these changes I was still getting a horizontal fold across the back at the sleeve area. (Super crappy photo below so you can get a general idea what I'm talking about.)
6. Shortened bodice by 1/4".
Took a scant quarter inch off that the bottom of the bodice. This length probably could have been left on because I ended up lining the bodice.
7. Shortened skirt by ????
OK I do know how much I shortened the skirt, it's just different in this muslin than it is in the final dress. The muslin was shortened by 6" which turned out to be too short with the bias sucking back up. On the final dress I shortened the skirt by 2".
Here's what all those adjustments look made up in the final muslin.
Part 4 "The final dress" post will arrive when ever I get a photo opportunity. So far non rainy days have been few and far between and usually happen when I'm the sole parent around. Let's hope the next one collides with some toddler free time and maybe semi-warm temps.
