As promised, here is my really big post of pattern notes and adjustments for Simplicity S8941 1790s to Regency Round Gown and Open Robe pattern.
This pattern was originally designed in the 1790s style, with a peaked back and full gathered skirt. As is Simplicity's preference, it was designed to be worn with a modern bra, but can also be worn with a 1790s or Regency corset.
This period of dress is an "easy" one to pattern because there is no tricky waist fitting - BUT, there is still the bust, sleeves, and overall length to consider. So let's get into how to make these adjustments, along with a few others. I've made some handy diagrams -
Also in relation to the peaked back - there is a flaw in the pattern for the straight skirt without the train. To account for the center back peak, you need to add about 1 - 1.5 inches to the center back at the top. The fix is shown above.
Time for sleeves. We all have different length arms, so here's how to adjust the sleeves to fit you better. The key here is that the top of the dart should be right on your elbow. If it's too low (as seems to be the case for most), shorten the upper part of the sleeve as above. Do this for both the short and long sleeve options.

I hope the above fixes and adjustment help! We want this pattern to fit everybody, but as with all patterns some tweaks usually need to be made for your unique shape.
For more information on how I made this gown, with all of these adjustment, by hand in one weekend, check out my dress diary on the 1790s Vigee-Lebrun gown.
