Bernard Boutet de Monvel (1881-1949), Wikipedia entry
here, was a highly successful portrait painter and fashion illustrator whose mature style was precise, spare, somewhat geometrical (for illustrations) in works that were carefully composed. I find his drawings more interesting than his paintings, though most of his works are very good examples of Art Deco / Moderne style.
Below is some of his portraiture.

Similar costume to the unidentified subject's above. (Or might that have been another portrait of Mme Champin? Hairdos and facial expressions differ, but that's not conclusive evidence.) This was probably painted around 1948, to judge by her hair.
