This picture belongs to the series of Matisse’s odalisks, which is characterized by a contradictory combination of simplified body shapes and exquisite ornaments that make up the background and the scenery of the work.
By the way, Matisse posed for this “Eastern” picture of a completely European woman, reincarnated into an “Odalisque” – externally and internally. However, this has already happened – the same Engra in his famous “Big Odalisque” depicts a European woman.
