Make an Apron-Front Regency Gown! (Part One)

I decided last August to make a new apron-front gown, basing it upon several gowns I've handled in person, plus an extant garment in the National Museum of Australia that I found online with detailed photographs.This time, I've used my Elegant Lady's Closet pattern as the base, since it has no back opening to begin with and features the more fitted long sleeves I planned to use for my undersleeves and the short, puffed ballgown sleeves I'd use as the over sleeves.
