A classic dressy but comfy and loose one size cardigan fitting the S M L sizes, with special twisted & bobbled border at each open side.
It can be loose or smart thanks to the silk. Worked in back & forth from one piece, top-down to underarms, divided in 3 parts, the sleeves worked in round separatly.
A special baroque musical design at the back (as cello holes).
No buttons, no button holes, just close it with a nice spindle.
