The pattern is self-drafted. It is another simple shape, a basic bodice, to which I drafted a little collar to add some interest.
Since I find the raw edge of linen scratchy against my skin, I decided to sew flat fell seams for the side seams. For the armholes, I created bias tape from the same linen fabric. White fabric tends to show the insides and I just didn't want a large dart take-up to show through to the outside so I trimmed the dart and finished the edges of the dart with a blanket stitch by hand.
It is amazing how hanging on the hanger, the neckline looks like it would be so much lower but on the body it is not. I will be making this blouse again but next time, I will lower the V-neckline further to make it look more like what you see on the hanger.
Speaking of the neckline, the V-shape creates a bias edge that is prone to stretching while handling. To prevent this from happening, I fused straight grain fusible tape along the edge as soon as I removed the garment sections from the pattern. I did likewise with the armholes and the shoulder seams.
With my next version, I will also bring the back darts closer to each other. They look a little too far apart to me.
I am rather pleased with how the collar turned out. It stands up as it curves around the neckline which you can see here:
If you would like to try your hand at drafting this collar, let me tell you it is the easiest collar ever to draft. It was all straight lines and then I rounded the corners. Measure from the center back to whatever point you decide you want it to end. In my case it was 11 inches. Then decide how wide you want it to be. In my case, it is 1 inch. As for the corners, I rounded them using a French curve but you can free hand the shape or use the edge of a can. I added 1/4 inch seam allowances for the collar and neckline.
I find that using a small seam allowance does away with the need to trim. With white clothes especially, you want a straight clean edge. I find I can cut a straight edge when I am cutting out with the pattern but no so much when trimming. I used lightweight fusible weft interfacing for the collar.
To attach the collar, make sure the center back of the garment neckline edge and the center back of the collar align. Then sandwich the collar in between the garment and the facing, pin and sew.
