Rompers for Infants

A romper is typically a one-piece with shorter or shorts-style legs, while a onesie (or bodysuit) mainly covers the torso and snaps at the crotch. A jumpsuit generally has full-length legs, making it a warmer option for cooler days. Browse related baby bodysuits if you'd prefer a torso-covering layer.

Rompers are a practical pick for babies because these one-piece outfits make dressing and undressing simple for busy parents. Many styles feature snap closures for quick diaper changes and soft, breathable fabrics that keep your little one comfortable while playing, napping, or exploring.

Baby rompers are usually sized by age range, so start with your baby's current weight and height, then size up if they're between sizes or growing quickly. Look for elasticized waistbands and leg openings, which provide a snug yet flexible fit that keeps up with an active little one.

Soft, breathable materials like cotton and linen blends work well for warmer days, while sweater-knit and critter fleece styles offer cozy warmth for cooler weather. Old Navy's rompers use lightweight, easy-care fabrics that allow easy movement and make laundry day simple.

Sleeveless and tie-strap rompers in double-weave or linen blends suit warm weather, while long-sleeve, hooded fleece, and sweater-knit one-pieces keep babies cozy in fall and winter. Layering a romper with a cardigan or hat extends its wear across seasons.

Rompers work for both casual playdates and special occasions. Choose ruffle-trim, denim, or embroidered sweater styles for a dressier look, or pair a simple romper with accessories to complete the outfit.

Look for rompers with snap closures at the crotch or legs, which allow quick access without fully undressing your baby. Elasticized leg openings also add flexibility while keeping the romper securely in place.

Rompers layer well with cozy cardigans, hats, and baby coats and jackets for outings in cooler weather. For a broader wardrobe, explore the full range of baby dresses and rompers.
