I wonder if, by adding their 'watermark', they've accidentally magnified the bottom corner of the picture? That's what it look like to me
It's like that in the paper copy too I believe from looking at scans. I wonder if they've tried to shave an inch off the side of her upper body. Just speculating here but perhaps she thinks her shoulders are too broad, which would explain the arm held up pose and maybe someone said they'd take an inch off the other side too and they've forgotten about her legs. Silly error really.. it's so obvious once you spot it. I suppose the saving grace is no one will be looking at her arm!
