the.com/drape

means To hang or arrange cloth (or anything cloth-like) so it falls loosely over something, or the loose fold of fabric that results.

from From the Old French 'draper,' to weave or make cloth, built on 'drap,' meaning cloth — itself from Late Latin 'drappus,' a word of uncertain, possibly Celtic origin. The same root clothes 'drapery' and the 'draper' who once sold fabric by the bolt; the verb-sense of letting cloth fall in folds came later, the word softening from the making of cloth to the way it hangs.
