What is in this image? Describe it as if you were explaining it to someone from the 15th century.

This image is a crafted illustration of a young woman, depicted in a graceful and somewhat fantastical manner. She appears to be dancing or caught mid-twirl, with her skirt flaring widely and her hair flowing dynamically behind her as if caught by a gentle breeze. The woman wears what might remind you of a simplified version of court attire a long, elegantly simple skirt paired with a tightly fitted bodice, and heels on her feet - not commonly worn in everyday activities in your time but perhaps seen in the courtly settings on special occasions. Furthermore, she wears a head covering that seems styled to both manage her hair and add a touch of modesty or decorum, common in attire of 15th-century ladies, though stylized rather differently here. Her posture and expression project a sense of joy and motion, aspects often appreciated in the artistic renderings of your time, though potentially with more allegorical implications. This image, while resembling line drawings that might be familiar to you, is executed with a clarity and simplicity not typically seen in the artworks of your era.
