I suppose. But, I suspect the string will tend to crease the fabric. Bunched up fabric should not provide a catch such as a sewn seam. The culprit in my learning experience was the corner of the flap covering the pocket. So, I look to avoid "hard" corners and edges that will catch the string. A lot of female target archers wear a chest cover on the string side. I believe no archer wants/needs anything adversely affecting the string upon release.
