In this upper body portrait by Frans Pourbus the Younger, Isabel Clara Eugenia wears the same gown as in her 1605 Pourbus portrait, but with a smaller and non-slashed ruff.
The headdress is spectacular. According to Norris, "Tudor Costume and Fashion," p. 754 (Dover re-issue 1997), the piled up headdress of pearls and jewels backed up with feathers originated in England, Spain's enemy at that time, but was avidly picked up in Spain."
