Imagine a dress that looks like a shirt! It's called a shirtdress. It's like wearing a big, comfy shirt that's long enough to cover your legs like a dress.
Usually, a shirtdress has buttons down the front (like a shirt!) that you can open and close, and sleeves that cover your arms. It may even have a collar like a shirt!
Sometimes, a shirtdress is made out of soft, flowy fabric that feels really nice and comfortable, like cotton or silk. Other times, it may be made out of a sturdier material, like denim or chambray.
Some shirtdresses have a belt or tie around the waist to give you a nice shape and make you look more fancy. Other shirtdresses just hang loose and are nice and casual.
Overall, a shirtdress is like a combination of a shirt and a dress, making it a versatile and practical piece of clothing that you can wear for many different occasions!
