A romper suit is a piece of clothing that looks like a one-piece outfit but has shorts instead of pants. It's like wearing a shirt and shorts that are connected together.
Imagine wearing a regular t-shirt and shorts. The t-shirt covers your top half and the shorts cover your bottom half. Now imagine if those two pieces of clothing were connected together, so you didn't have to worry about your shirt coming untucked or your shorts falling down.
That's what a romper suit does. It's a one-piece outfit that's easy to wear and move around in. You can wear them when you're playing outside or going to a party. They can be made out of different materials like cotton, denim, or even fancy fabrics like silk.
Romper suits come in all different colors, patterns, and styles. Some have buttons or zippers while others just pull on over your head. They're a fun and comfy way to stay stylish and play all day!
