This Titian portrait was painted around 1509.  It was previously believed to depict Ludovico Ariosto, but it is now believed to be Gerolamo Barbarigo.

The clothing depicted here on this male sitter is that of body linen, an outerwear garment that is quilted, and a cape or overcoat.  

The body linen has a circular neck that takes the volume of the body panels and sleeves and pleats it down to a band around the neck.  The circular neck appears to be lower in the back than the front, but this is an illusion because on a human, necks, and heads sit farther forward on the torso and are not centered front to back.

The outerwear is a blue fabric that is heavily quilted.  The sleeve shows a large, voluminous sleeve at the top of the arm that pleats to a narrow gauntlet-style sleeve below the elbow.  This would indicate a 2 part sleeve that is sewn together, not tied or laced.   The upper sleeve has a few large pleats into the shoulder strap that forms the square neckline of the garment.  The upper sleeve is much more heavily pleated at the bottom, below the elbow, into the tighter gauntlet-style lower sleeve.  

The cape or overcoat is of dark fur or possibly velvet.  It is slung over the sitter’s back arm and just hanging loose over the back of the sitter.
