Now correct me if I am wrong but doesn't this look like an A line but more to the straight skirt shape?
So why does the line drawing look like this?
And the hem width is really wide.
I have my suspicions.
I once helped unpack Big Four fashion show samples and saw much evidence of "tweaks" of the pattern to achieve a more camera ready look.
Probably not the biggest mystery to be solved on the planet today but one I am thinking about.
