The Great Pattern Review has like 6 reviews of the Period Impressions polonaise, and a few of them give advice regarding authenticity and any changes they made. I think those more experienced seamstresses would be a better judge than I of an 18th century pattern. But one day perhaps I'll know 18th century as well as I do bustle *wish*.

Anyway, you know I'll post progress (ahemHELPINEEDHELPahem) posts as I go along.

Your blue zone front gown is one of my favorites, by the way. I love it!
