Bianca Capello De'Medici (possibly) 

This portrait, possibly depicting Bianca Capello de' Medici, was created by Alessandro Allori, a Florentine painter active in the late 16th century. The painting features the sitter in a three-quarter view, showcasing her elegant attire and delicate features. The rich color palette, intricate details of the clothing, and subtle yet nuanced portrayal of the subject are characteristic of Allori's style, which blended elements of Mannerism and realism. While the exact identity of the subject remains uncertain, the work exemplifies Allori's skill in capturing the essence of his sitters, making it a significant example of Italian Renaissance portraiture.
