means A flat figure cut from paper, dressed by fitting separate clothing cutouts onto it using small folded tabs.

from Straightforward compound: paper + doll. Jointed and dressed paper figures as playthings trace back at least to 18th-century Europe, with printed sheets of costumes gaining popularity through the 1800s as cheap paper and printing made them easy to mass-produce; the tab-and-slot dressing method became standard as the toy spread. The phrase later got borrowed figuratively for anyone treated as interchangeable with their clothes or image rather than as a whole person.
