I made an 1880s polonaise, the costruction, fit and trimming

In this video, I make an 1880 polonaise gown and briefly explain what a polonaise actually is. The bodice is constructed with sprung boning to ensure a smooth fit, I show you how to do it and how it affects the fit of the garment. And focus on showing you how I make that smoothly fitting armscye that is quintessential to the natural form era and show you how to make the crochet fringe trim I used for this gown. the corset I wear under this gown: https://www.youtube.com/watch?v=YM6bSkhXcbA&t=400s the pattern I use can be found here: https://i.pinimg.com/564x/ec/fb/14/ecfb1468db2b90703f143edfeb496f2d.jpg The book I used for construction reference: https://www.amazon.com/Fashions-Gilded-Age-Accessories-Dressmaking/dp/0963651765
