Hopefully you can open up that first pleat and correct that curve... Looks a lot like something that happened on the test fabric when I first figured out how to machine stitch from behind to keep the stitching invisible - somehow one of my pins only went through the top fold of fabric... When one layer of fabric slipped as I was sewing, it left a very similar curved line.
Fingers crossed that whoever tried to squeeze so much shaping into one pleat didn't do any chopping.
I'll be watching this thread very closely.
