Here it is halfway done, trying it's best to hold itself up on my female dress form.
And now the sleeves with their vents. These were pretty easy, with satisfyingly good results. The buttonholes are not to be cut, with the buttons being sewn right onto them through the layers. Personally, I think it would be easier to sew the buttons on with the vent open and just go ahead and use the buttonholes. But I suppose it looks neater not being cut.
And some fun sewing room pictures.
