You cannot count all hoodies as business casuals, but there is one that can be. Indeed, cashmere is prized for a reason. In the hoodie form, they are not only comfortable and breathable, but they also make you look rich by association. They give you both a lazy and formal look; it depends on how you layer them and the outfits that you pair them with. For example, you can wear grey colour cashmere hoodies and pair them with smart trousers to look chic smart. But make sure you do not look out of the place when you wear one. Make proper predictions about the place and theme you are going to.
