I love the way the interlined silk hangs, its exactly what I'm hoping for. I got a little nervous about how the net looks over the silk - the original dress had a layer of striped tulle under the net, which gave it a more textured look. However I'm not going to worry about it now, I'll wait till I've got the appliques on because I can always add more detail if I need to.
The back fastening is the part which required the most thought - its consists of a hidden zip (as in hidden by a placket, not an invisible zip which wouldn't be strong enough) and then rolleaux loops and buttons (which aren't sewn on yet). I haven't decided what to do about loops for the top lace section, but at the moment I;m thinking either thread loops or possibly elastic. They won't really be rquired to take any strain, so I have a few options.
Jobs for next time:
Fix the underskirt (thanks mum for unpicking it)
Add removable train support
Sew in the tulle godets
Take in the bodice as required
Hem the silk skirt
Set bustleing points (so I can make sure the stitches joining the tulle to the silk at these point are covered by motifs.
