One things kids will do? Play. As such, it's fitting to put them in an item designed for this very action: a romper. Romper comes from the word romp, which means to play or frolic. A romper is a piece of clothing made of a shirt with attached shorts or pants. Rompers are especially popular as kids clothing, but are also seen in women's fashion online. This piece of kids fashion is comfortable and convenient, a staple for babies. Rompers can be worn as sleepwear with some babies socks to keep them warm, or during the day with kids shoes and a jacket on colder days.
