So why do I get neck gape? I think it's because of my narrow shoulders and hollow chest, paired with my full C-cup bust. A logical solution for many people is simply to drop down a pattern size and perform an FBA (full bust adjustment) and adjustments further down. For some reason, there is a negative association with altering the neck and shoulders, and IMO, it really is one of the easiest places to alter a pattern with many styles. It's simply the way I prefer to alter patterns for my figure, although it seems contrary to what most will recommend.
Therefore, when I buy sewing patterns, even though I use the correct size for my figure, I often end up with neck gape. This is quite an annoying problem, yet such an easy and simple fix.
I am going to show you two (I have three total however) methods today that I use to remove neck gape on patterns. The first is VERY simple, the second is a little more work, but targets the exact area. I don't use one exclusively, it really depends on the pattern and how much gape needs to be removed. If it is small amount and depending on the pattern style, I use the No. 1. If the amount to be removed is more than a 1/2", I use the second method.
The two methods are:
1. Shifting the pattern's center front
2. Dart and Tranfer
--------------------------------------------------------------------------------------------
METHOD NO. 1:
Here is a miniature sample of a pattern front with the bust apex marked as a dot. The pink construction paper is the "pseudo" fabric. The pattern's center front (CF) is placed on the fold.
Let's say I have a small amount of neck gape that I want to remove, not more than a 1/2". What I'm going to do is shift the top, CF of the pattern over to the right, off the fabric fold a 1/4". Yes, I did say a 1/4". Remember, this is only half the pattern. A 1/4" will actually be a 1/2" removed from the entire front neckline. The 1/4" shifted over to the right is illustrated in the picture below. Notice the fold of fabric under the pattern is marked with a broken line.
That broken line will now become the new CF. I will mark a new grainline marking and cut off the excess as shown below. This will complete Method 1, and very easy method to remove neck gape.
-----------------------------------------------------------------------------------------------
METHOD NO. 2
This method is a more precise method, targeting the exact area of the neck gape when it is more than a 1/2", and transferring that excess somewhere else. That "somewhere else" in my sample below is a bust dart, although it could be rotated anywhere on the bulging block (anywhere around the bust apex).
First, here is a picture of my sample pattern front:
Next, I draw two lines: one from the area of the neck gape to the bust apex, and one from the side seam to the bust apex as shown below.
After drawing these two lines, I cut them with a scissors *almost* to the bust apex, leaving a hinge of the pattern right at the bust apex. In the picture below, notice how I am lifting the upper piece that has been slashed on both lines. It doesn't lift up completely because of the "hinge" at the bust apex.
Now I will slide the lifted piece over to the right, let's say 5/8" inch for this example. This will remove a total of 1 1/4" of neck gape. Yeah, that would be a lot. But it happens sometimes. Notice in the picture below, when I shift top of the pattern over to the right to remove the gape, a new dart forms at the bust. OR...if you have an existing bust dart, it will make your existing dart bigger. The broken line represents the amount that is removed.
Next, I will true the neckline and fill in the new bust dart with tissue as shown below.
That completes Method 2.
Both are different methods that basically accomplish the same thing--removing that annoying gape. This method can also be used on the back bodice as well. I usually remove back neck gape and transfer it to a shoulder dart or convert it to a princess seam by transferring the neck gape excess to both a waist and shoulder dart combo.
Hope this helps in your quest to remove neck gape :) !
