The chemise dress is looking lovely! I really like your idea of lining it. If I remember correctly, I dont think I gathered the fabric along the shoulder strap, but instead attached the drawstring at the shoulder seams. Does that make sense? In the end though, I had to make the front gathers more stationery, so I bound the front edges, but left the drawstring free to take up any slack. Again, Im probably not making sense and since your dress looks lovely anyway, Im probably not helping at all. ;)
