A man with curling, light brown hair and a thick moustache gazes outward from the centre of the composition, his head turned slightly to his left. He wears a striking red doublet that dominates the lower half of the oval panel, its surface marked by a row of decorative fastenings running down the front. A broad, white collar with crisp folds sits atop his shoulders, its brightness catching the light and contrasting sharply with the deep, warm red of his garment.

The background is a soft, dark brown, subtly modelled to suggest depth but free of any objects or distractions, focusing all attention on the sitter’s face and attire. Light falls from the left, illuminating the man’s forehead, nose, and cheek, and softly modelling the flesh tones with smooth, blended brushwork. The handling of paint is especially refined in the rendering of his skin, where delicate transitions of colour and tone create a lifelike presence.

His eyes are lively and direct, with a hint of moisture and a glint of reflected light, while his lips are closed and his expression is calm but alert. The artist’s signature and the date appear in the upper right, lightly inscribed in the background. The composition is tightly cropped, with the man’s head and shoulders filling the oval format, and the background receding into shadow.

Subtle variations in the red fabric and the play of light on the white collar reveal the artist’s attention to texture and material. Portrait of a Man Wearing a Red Doublet was painted by Rembrandt in 1633. The work is also known as Portrait of a Man in a Red Coat, as described by The Leiden Collection. The subject is a single male figure, as indicated by the genre and description.

The painting belongs to the portrait genre, depicting a man in contemporary dress of the early seventeenth century. The painting is executed on an oak panel, using oil paint.
