There are a couple areas of creativity where I have achieved a pleasing level of competence. I can sew or knit or write something entirely new, and it mostly turns out the way I envision it. Other areas I have not gotten to this level of freedom, and probably will not live long enough to achieve it.
But I have sewed and altered so very many garments that I know how to go about this one. The pattern for the body of this dressing gown will be in four pieces, two front and two back, each mirror images of each other. This allows for pleasant shaping, and a side seam gives me a place to insert pockets. The sleeves will be a single piece, again mirror images right and left. The center back box pleat will be a long single rectangle of fabric. (Should I make it wider at the bottom, a wedge? TBD) The scalloped lapels, right and left, will curve around the neck and widen at the bottom. Like this one:
At the back, above the central box pleat, the back collar will continue on around being scalloped. Notice in this magnificent example that the quilted contrast lapels are actually seamed onto the front. I won’t be doing that, because a scalloped seam in brocade is far too much like work. And are not the frog fastenings glorious? I don’t think I have the skill to do these. Before I actually start sewing I am going to have to come to a decision about the fastenings.
But, in the meantime, newspaper patterns. It is easiest to make patterns for one’s own self. You can measure yourself at any moment, and you presumably already have a wardrobe full of garments that already fit you. By copying the neckline and armhole of an existing garment onto newspaper I get this. In the middle behold the two torso pieces, front and back. The scalloped front lapel is beside them, and on the other side is the sleeve. The sleeve cuff, evenly scalloped, is on the far left and the back collar, also scalloped, lies at the top. I have cut this without the seam allowances. Before I actually move to the fabric I’ll do a little measuring, to be certain I’ve gotten enough width. You can sneak in length, but width is difficult to fix. Is the skirt going to be wide enough?
