Oh dress, so close!
I skipped the back darts for now. I tend to finish clothes, wear them out in the world once then go back and fix what bothers me.
So I left my dress-from-dress in the sink this morning, soaking in a little Woolite to get out both the red sewing markings and the vintage stink.
The finished little guy might need darts added in once it’s dry and on. I also plan to put in side belt loops I think I will quickly scrounge up from cotton crochet thread to hold the existing belt from the original dress.
