The UNO Baby Romper is a modern everyday one-piece designed around simplicity, contrast, and connection. Named after the word uno, meaning “one” in many Latin-based languages, this baby romper celebrates beginnings, first moments, and the beauty of keeping things essential.

Designed in a bold black and white color palette, the high-contrast look feels timeless and graphic while remaining easy to wear. Made from soft, breathable cotton knit, this romper is gentle on sensitive skin and comfortable for crawling, playtime, naps, and rest.

Thoughtful details like a Henley-style button placket, inner-leg snaps for easy diaper changes, and a functional kangaroo pocket make this piece as practical as it is intentional. The relaxed fit allows babies to move freely throughout the day.

Designed as part of our small batch collections in Los Angeles, the UNO Baby Romper reflects our belief that everyday baby clothing can feel meaningful without being complicated.
