It is already a stunning game! I am a costuming major and so much of this game is just the little bits of the process i love the most (i'm not the best at initial sketches and drafting and being so short i struggle with cutting tables not to mention that its just expensive). The only additions that I could see being useful/more realistic is a sort of continuous seam system. I found it frustrating to stitch every single skirt panel to the waist after i had already stitched all the skirt panels to each other. It would also be cool to see some sort of applique or trim adding portion. Finally, it would be cool to see some sort of difficulty scale as you learn more dress patterns such as darts, gathers, gussets, boning or extra pieces like trains and capes.
I can't wait to share this game with my costumes professor once college starts back up.
