In María Teresa (1638–1683), Infanta of Spain, we see a young girl dressed in an elegant gown adorned with intricate lace. The color palette is rich, featuring deep reds and golds that highlight her royal status. Her expression is calm and poised, suggesting a sense of dignity.

The background is softly blurred, focusing attention on her figure and attire. The painting is executed in oil on canvas, a common medium for Velázquez. It measures approximately 100 x 120 cm, allowing for detailed representation of textures and fabrics. The artist's brushwork is precise, capturing the delicate lace and the softness of the fabric.

The use of light and shadow enhances the three-dimensional quality of the figure. Diego Velázquez, a prominent figure of the Spanish Baroque, painted this portrait around 1650. María Teresa was the daughter of King Philip IV and later became the Queen of France. This work exemplifies Velázquez's skill in portraying royal subjects with both realism and grace.

An interesting fact is that this painting was part of the royal collection and reflects the importance of royal portraiture in the 17th century.
