Hi!
I've really been enjoying this game so far! I'm a costume designer/seamstress so it's right up my alley!
Most of the things I would suggest are things you've stated you're considering (more silhouette options, sizing, more fabrics, ect.)
I also think adding details like embroidery, piping, matching accessories (being able to make custom bags or dye shoes would be a neat touch!) could be really interesting. Additionally, adding sewing details like stitching darts or a gathering mini-game would add a touch of realism if that could be pretty neat.
A little bug I had:
-My second dress did not let me stitch it and was stuck on -274872384783 or so quality lol. It was accepted by the customer though
