I am so excited! I think I actually have the fit of this bodice now!
When I got up this morning, I decided that what I needed to do was to lower the bust curve, but I wasn’t sure how. I looked at the pattern pieces and how they were graded up to the next size. My lower bodice is cut in a size 36. I decided to start with altering to a size 40 cup. The first thing I did was trace the lines for the two lower bodice pieces top edges onto tracing paper. I then traced those lines onto the muslin so that I could make sure that the cup would line up with the new curve that I drew. I then traced the size 40 cups and left a generous seam allowance all around (good thing!) I sewed in one, and could see that it was still too small. You can see the blue line where I redrew the bust curve.
Next, I added to the height by adding to the horizontal seam line across the front of each cup.
This seemed like it would work, but I need to try it on. My dress form is not exactly my shape, so I wanted to try this thing on my real body to make sure.
At this point, I sewed the back pieces together and added a long zipper so I could get it on and off easily. After trying this thing on about a dozen times, I kept making little alterations.
My final alterations were to do this:
(only the right cup has the final alterations on this muslin)
- Keep the size 36 lower bodice
- add 1/2 inch to the top of the lower cups and the bottom of the upper cup for a total increase of 1”
- Used a marking pen to add to the sides and center front of the cups. A total of about one to one and a half inches.
- I also added to the lower portion of the cups which also changed the shape of the cups. I sewed these changes in by hand and marked them with a marker after they were sewn. (Unfortunately, I did not use permanent marker, so you can see where the ink spread when I turned my iron upside down to press a curve and water spilled out!)
- I also took a small dart in the outer part of the upper cup. I was having a little gapping there.
- I pinned out almost an inch in the back that I all remove by making a sway back alteration to the back pieces.
- I may also have to take a little out of the side back seams, but I will be able to do that after all the layers are put together.
Now the trick will be to take this apart and make all the changes onto the new pieces. These cup pieces are so messed up and only the right one is the correct one. I think I will need to trace a new set of cups based on all of my changes.
