Brave Fine Art has dated this piece to the 1920s.
It’s an interesting painting for several reasons. Firstly, the composition has us standing by a chair looking down at the right side of her body.

Secondly, the artist, Oswald Poreau (1877-1955), was primarily a landscape painter and isn’t known for nudes - so maybe this is an intimate portrayal set within a home? There’s certainly a degree of sensuality to it.

And thirdly, why is she wearing boots? Had this been discussed during the sitting? Was it her idea or his?
Oswald Poreau was a Belgian artist who trained at the Royal Academy of Fine Arts in Brussels under Joseph Stallaerts.
