Collection: Big & Little Brother and Sister Shirts

Sibling shirt guide

• Best seller: the Little Brother bodysuit sold 147 in 2025, our most popular sibling style.
• For the baby: Little Brother and Little Sister bodysuits.
• For the older sibling: Big Brother and Big Sister tees, plus Big Brother and Big Sister bodysuits for siblings who are still babies themselves.

Size tip: for the big sibling, buy the tee one size up if the photos are a few months away. For the new baby, 0–3M fits the hospital and first weeks, and 3–6M lasts longer.

Frequently asked questions

When should the big sibling wear their shirt?

Most families use it twice: in the pregnancy announcement photo, and the day the older child meets the baby at the hospital or at home.

Do the big and little styles match?

Yes. The lettering and colors are designed as pairs, and both come in natural and clay, so siblings match in photos. See more coordinated looks in Sibling Matching Outfits.

What's the difference between the natural and clay colors?

Natural is undyed cream organic cotton. Clay is a warm, earthy tone. Both use the same certified organic cotton and fit the same.
