Baby Boy Romper FAQs

What is a baby boy romper?

What is the difference between a romper, jon jon, and bubble?
A romper is a broad one-piece clothing style that may have sleeves and short or long legs. A jon jon is traditionally a shortall-style garment with shoulder straps and defined leg openings, while a bubble has gathered or elasticized leg openings that create a rounded silhouette. Cecil & Lou offers each style in separate collections to make these classic boys silhouettes easier to shop.
