Though coined in the middle 19th century, the adjective Rubenesque has flourished during the last decade or so as a polite way of saying plump, full, or round, especially in describing a woman. The word refers to the Baroque painter Peter Paul Rubens, many of whose works depict full-figured women. The word should properly be Rubensesque—and the OED, for one, lists it with the extra s—but it is only rarely spelled this way.
The R in Rubenesque is usually capitalized. If the word remains in the language much longer, it may eventually lose the capital.
