I finished fixing both sheers (this includes practically remaking the green and white sheer), and I'm feeling much better about my situation. It only took me a day of focused sewing to get those done. Here's what's left to fix:

*ball gown: re-hemmed in front only
*sherbet dress: guimpe to be made and attached, eyes attached, dog leg skirt closure redone
*gold silk dress: finish repleating skirt, take in bodice

To make:
*sheer fichu
*black silk belt
*pair of drawers

I can do it...
