noun
stole
STOHL/stˈoʊl/
A long, narrow garment worn around the shoulders.
An ochre stole rests over the shoulders of her navy dress.

Etymology
The older robe meaning narrowed to a scarf-like garment worn by clergy. The later fashion stole took its name from its resemblance to that clerical garment.
In context
What is not optional but does take different forms, is the stole, the long scarf-like cloth worn around the neck.
