I fitted my over-bodice! Self fitting a button back bodice is generally not recommended, but the main challenge was due to my scoliosis (twisted spine). The calico toile was fine, but the softer tulle needed a lot of encouragement not to follow my backbone!
The alterations were actually fairly minimal - a slight adjustment to the shoulder slope (different on each side!) and cutting the back armholes a little bigger to give a bit more ease.
Before and after pictures:
The 'before' shot is exaggerated by the fact that the stabiliser is still in place, and I used a back zip for my first fitting, but it is still a dramatic difference for such minimal changes.
Once I have the lace motifs in place I'm hoping my deformed back won't be quite as obvious! First I need to stitch the (currently hand-tacked) seams, remove the last of the stabiliser, and sew the buttons in place.
