After playing for several dozen more hours(this is a really fun game) I have a few more suggestions!
A way to quickly get lace around the hem or around the edge of sleeves would be very helpful. At the moment, trying to get around the edges of shorter sleeves is pretty buggy and has a lot of clipping issues.
I would love to be able to use the coloring function to add the patterns to the sketch.
Skirt 6 takes about 25-30 meters of fabric if you aren't squeezing every last ounce of space out with the patterns. While it is a very beautiful skirt, I think a skirt with similar volume or something similar that requires less fabric would be good.
Some skirts have a waistband and some don't. I really like the waistbands and would like to be able to add them to some of the simpler skirts. Maybe a wider ribbon could be used to add that without changing the patterns?
None of the black fabrics are really all that dark. This is especially noticeable when paired with the black lace, which is several shades darker. At the moment, the Dark Gray Cotton, the Onyx Black Silk, and the Ink Black Wool are all basically the same color.
The lighting on the mannequin is really harsh at the top. Using a light fabric for a collar makes that area really bright and kinda hard to see.
I love this game a lot and I'm super excited to see more!
