Undershirt

An undershirt is a special type of shirt that you wear underneath your regular shirt or clothes. It's like a secret layer that helps protect your body and clothes from sweat and dirt.

Undershirts are usually made of very soft and comfortable fabric that feels nice against your skin. They can come in different colors and styles, but most of the time they are plain and simple.

When you wear an undershirt, it helps to absorb sweat and keep you feeling dry. It also helps to protect your regular clothes from getting stained or dirty, especially if you're doing something active or messy.

Overall, an undershirt is like a superhero outfit for your body. It helps keep you comfortable and clean, even when you're out and about doing fun things!
