For the best fit on the Iris Bralette, you will want the vertical seam to fall in line with the apex.
What is the apex?
The apex is the fullest part of the bust, usually where the nipple lies. In the photo above, you can see that the vertical seam aligns with the fullest part of the bust, and also aligns with the vertical seam on the dress form.
How to Alter the Pattern
