King Charles painted in a smaller version of the picture that would eventually become the famous portrait in his robes for the Order of the Garter. It’s earlier than our period, but worth looking at for the detailing of his clothes which I’m pretty sure are accurate given the way Mytens (or one of his followers) has also rendered the texture of the carpet and the sheen on the table covering.
His hat is generously plumed and his falling band (that is almost completely lace) lies over the red and white robes of the order. His shot silk doublet is high waisted and of the 1630s style with sharply angled tabs and ribbon points. You can see how stiff the tabs are by the fact that the right hand edge of his robes are held back behind the right front tab. The sleeves are slashed and gathered in a way that accentuate his slender arms but also shows the fine linen of his shirt beneath. His matching breeches are quite closely cut and the silk seems to have been slashed or pinked as an extra decoration. He’s also wearing a very fine pair of white shoes with jewelled rosette ties and some oddly mismatched blue hose on his lower legs.
