A young girl with pale skin and flushed cheeks sits upright, her body turned slightly to the left while her face looks forward, framed by thick, curled hair adorned with red and white flowers and pearls. She wears an elaborate cream-colored dress that spreads out in a wide arc, decorated with delicate embroidery, pearl strands, and gold ornaments at the bodice and sleeves. Her left hand rests gently on her lap, holding a white handkerchief with lace edging, while her right arm extends outward, the hand poised above the dark green background.

Two watches hang from orange ribbons at her waist, one round and one oval, their faces visible against the pale fabric of her skirt. The light falls from the left, illuminating her face, the upper part of her dress, and the handkerchief, while the background remains deep and shadowed, creating a strong contrast that sets off her figure. Fine brushwork captures the sheen of the satin and the texture of the lace, while broader, looser strokes describe the folds and volume of the skirt.

The composition is carefully balanced, with the sitter's head placed just off-center and her arms forming a gentle diagonal across the canvas. Small details, such as the gold brooch at her chest and the intricate red embroidery on her sleeves, are rendered with precision, drawing attention to her status and wealth. Portrait of the Infanta Maria Theresa of Spain was painted by Diego Velázquez between 1652 and 1653. The sitter is Maria Theresa of Spain, shown here as a young teenager, her solemn expression and formal pose reflecting her royal status.
