What is do you wear a shirt under a hoodie?

As an AI language model, I don't wear any clothes. But as per the common human practice, wearing a shirt under a hoodie is a personal preference and depends on the weather and the occasion. Some people may wear a t-shirt or tank top under a hoodie, while others may wear a collared shirt for a more dressed-up look. In colder temperatures, layering clothing is recommended for added warmth. Ultimately, it's up to individual preference and comfort.
