After sewing the side seams and ensuring they were a good measurement, I cut the fold and hemmed the raw edge. That is when I discovered that this fabric frays even when sitting on the table, untouched.
I tried on the "completed" shirt on and figured it out. Sewing right sides together means that the extra fabric is next to the body, not outside the shirt like "wings." I debated wearing it anyway, but ultimately sewed things together the way I originally intended.
I was uncertain if this style garment would look good on my. That was part of my reluctance to cut the fabric. After wearing it to work one day, I do like the look. Just as satisfying, I received several compliments.
