This is a Ben Zuckerman suit, in camel hair, with a large fur collar in what is possible fox. The jacket is boxy, and double-breasted, with pockets near the waist. The skirt has a banded waistband and is a typical Zuckerman- simple in design to allow the jacket to shine.
Camel hair is a type of cloth made from camel hair, and is classified as a specialty hair fibre. The outer protective fur (guard hair) is coarse and inflexible and can be woven into haircloth. Guard hair can be made soft and plush by blending it, especially with wool. The camel's pure undercoat is very soft, gathered when camels molt in the warmer seasons, and is frequently used for coats.
