In the above picture I have lowered the side darts 1 and 1/2 inches and shortened the waistline darts 1/2 inch.
In this photo you can see that I have too much room above the bust.
Way too much fabric. Like most women, my upper chest area is sort of concave. Not really concave, but you know what I mean.
Another alteration I've already made to Muslin 2 that worked is back neckline darts about 2 inches long. So the back is fine.
At this point I think I need to remove about 1/2 inch in width from the shoulder to the bustline on each side of the bodice front. I also need to take in deeper side seams. I think the darts are working now, but I won't really be able to tell until I take in the side seams.
If you see anything I've missed, please leave a comment! Help!
