There is no fabric tag, but I think the top is made of polyester blend satin.
Skirt is made of small-whale corduroy.
Jacket is of a medium whale corduroy.
The dress and blazer are both fully lined.
The dress has pockets! Also features princess seams, a straight A-line skirt, stand up collar and set-in sleeves that end in cuffs that snap close. Dress closes in the center with a back plastic zipper.
The blazer has notched lapels and long set-in sleeves. Both garments are fully lined and still has the original belt.
Fun fact: Claudia was the name of George Halley’s wife! Personally, I think this is a rather strange, interesting outfit.
