If you find that you have tightness, stress lines, or a flat spot at the apex, you might need to increase the projection.  Projection is how much/far the breast sticks out from the body.  ​

The following pattern adjustment will work for both the Zenita and Annika Wireless Bras, or any vertical-seamed bra.  Shown below are the Inner Cup/Outer Cup pieces for Zenita.  I recommend applying the changes (and creating a test fit sample) in just these pieces before applying the changes to the Upper/Lower Inner and Outer Cup pieces of Zenita. 

To add projection, we will add more at the apex and blend into the lower and upper parts of the seamline.  Don’t add too much here, as you can end up with a very pointy cup shape!  After making your pattern adjustments, measure the seamlines to be sure they still match in length.
