According to the Riddled Dream Machine, she is dreaming of the Empress' Second-Hand Clothes. These are not quite so fine of weave or subtle of thread as her new clothes so they can still be seen by fools, but only half the time.
The artist here is Paris Bordone, previously featured at Riddled for his fondness for painting his ladies with post-orgasmic flushes on their breastal region. Bordone was a student of Titian, who evidently only taught him how to paint a single face. Or perhaps this is a Twin Study, painting identical twins with and without the flush to see if it makes them look sexier.
