I have a purchased top similar to this which I like very much. It has sort of a shawl collar and a center front seam. The front on the purchased top is doubled fabric, so in essence it is self-facing / self-lining.
This being Kwik Sew, the pattern paper is thick, and I usually trace off my size onto tissue. I was amazed – no fitting changes needed at all. A medium fit right out of the envelope. The only thing I did was to stitch the center front seam a bit higher. I’m past the age where showing cleavage is de rigeur.
If anyone else is interested, the pattern is still in print as well.
