Linda F and Nancy K, kindly commented on the fit. There seems to be something wrong with the shoulder and armscye, this being the North American term for armhole, sounds fancy! I have already taken in the shoulder a lot. When I layed my altered pattern piece over the original pattern, the shoulder and armscye were smaller than the smallest size "A", which gave me a warm fuzzy vanity sizing feeling, as I had originally cut a "B". I am very happy with the neck and collar fitting, so chose to try a narrow shoulder adjustment, rather than redraw the upper bodice of the pattern to a smaller size, which was suggested in another fitting thread at Stitcher's Guild. The narrow shoulder adjustment amuses me, as I have always thought I have very broad shoulders, however, possibly the rest of me has caught up to, and indeed surpassed them! My shoulders also tend to squareness. I do not usually adjust for this, but seeing as I was in my fitting book (above) I thought I would go the whole hog and adjust for my square shoulders as well.
For the shoulder adjustment, I slashed (outside the dart) vertically from the shoulder, and horizontally from the bottom of the armscye, then crossed over the slash at the shoulder by the amount I wanted to take in. Then I trued the shoulder, and redrew this line with a decreased slope to allow for my square shoulders. I have cut out the blouse and hope to make it up tomorrow to judge the success of these alterations. I have not altered the sleeve again. I think there is enough ease already to allow for the very slight change this adjustment makes to the bodice armscye.
