The sleeve pattern for the Gray Blouse turned out to be one of my most interesting conceptions so far, having five, circularly lengthened, vertical darts worked into the head, providing girth along the otherwise straight-cut sleeve, and a number of folds at the base capturing that girth into the cuff, with the extra addition of an inverted box-pleat within the seam-line, to bring out even more flow towards the back of the sleeve, guided outwards with one last, horizontal, dart worked into the elbow side.
Good thing that’s your simplified line. >_>
