Baby Ribbed Collection: Onesies, Sets & Accessories

The Rai & Co Ribbed Collection is the heart of our range, and the place most Australian mums start. Built on our signature ribbed fabric, every piece has a buttery-soft, stretchy texture that holds its shape wash after wash and feels as good on day one as it does on the hundredth wear. From full-length footed onesies for newborns to matching two piece sets for toddlers to age 6, the Ribbed Collection covers every age, every season, and every occasion, all in a palette of muted, minimalist tones designed to mix and match across the entire range.

Ribbed Onesies & Jumpsuits

Our Plain Ribbed Onesie is our bestselling product, a midweight, full-length footed jumpsuit with a two-way hidden zip, fold on/off windproof feet, higher neckline, and hand mittens on newborn sizes. Available in 9 colours from sizes 0000 to 1, it's the onesie Australian mums reorder in every size. The Frill Ribbed Onesie adds delicate frill detailing to the same practical base for a more feminine everyday look. Both are suitable for everyday wear and sleepwear, gentle on sensitive and eczema-prone baby skin, and built to be passed from one child to the next.

Ribbed Accessories

Complete any ribbed outfit with our matching Ribbed Beanie and Ribbed Knotted Headband, both made from the same 95% Cotton / 5% Spandex ribbed fabric as the onesies, super stretchy and soft, and available in colours to match across the collection. Because the best baby outfit is a coordinated one.

FAQs

Are ribbed onesies suitable for newborns?

Yes, ribbed onesies are perfect for newborns because their soft, stretchy fabric provides comfort and freedom of movement. Our collection at RAI & CO is designed with delicate skin in mind, ensuring both comfort and style.

How do you remove stains from ribbed baby clothes?

Treat stains with a baby-friendly detergent and cold water before washing. Avoid harsh chemicals to maintain fabric quality.

Do ribbed onesies shrink after washing?

High-quality ribbed onesies are generally pre-shrunk, but it’s always best to follow the care label instructions. Washing on a cool, gentle cycle and avoiding high heat drying helps maintain their shape. At RAI & CO, our ribbed onesies are designed to last, keeping their softness and fit even after multiple washes.

How many ribbed onesies should I have for my baby?

It’s recommended to have around 5–7 ribbed onesies for regular use. This allows for quick changes throughout the day due to spills or nappy changes. Our ribbed onesies are durable and easy to clean, making them ideal for everyday wear.
