Frequently Asked Questions
How are Sunday Littles products designed to endure up to three times longer than typical children's clothing?
Sunday Littles products are made from a custom milled fabric that incorporates high-quality bamboo stretchy fibers. This unique combination enhances the durability and longevity of the garments. The elasticity of the bamboo fabric allows for greater flexibility and resilience, ensuring that the clothing maintains its shape and comfort even after multiple washes and wear. This design philosophy ensures that the garments not only fit well but also withstand the active lifestyles of children, making them a smart investment for parents.
Will your clothes shrink after washing?
No, our bamboo fabric doesn’t shrink. Bamboo fibers are naturally resistant to shrinking, so your Sunday Littles clothes will maintain their shape and size wash after wash.
Why choose bamboo fabric for sweat sets?
Bamboo fabric is incredibly soft, breathable, and eco-friendly. It’s gentle on sensitive skin, making it perfect for all-day comfort and wear. Plus, it's naturally antimicrobial, keeping your little one feeling fresh.
Are bamboo sweat sets durable?
Yes! Bamboo fabric is known for its durability and resilience. Our sweat sets are designed to last, holding up to multiple washes without losing shape or softness.
Customer Reviews
Super cute print and the fabric is next level. I also loved the fact that the quality and details were so good I felt like my son could wear it as a set out and about. I purchased the Halloween print with skulls and the pants also had pockets. I personally feel you can size up and it will still fit for a long time since you can cinch in the drawstring at the waist and the bottom of the pant tapers down so they don’t trip on them if they are a bit longer they just scrunch up and sit nicely. Definitely a good investment piece as they can get tons of wear out of it.

Highly recommend!! So soft, stretchy, great for longevity! Such great quality! And of course this print is even more stunning in person!!
We ordered the sweat set instead of the PJs for more/longer wear. It is very breathable and a lightweight fabric (not a sweat-type fabric). We sized up because our toddler is right between sizes. He can actually wear long johns underneath now and likely wear it on its own into spring because of how lightweight it is. Stitching, deisng, colours, print all seem to be nicely made. We buy lots of second hand, but when we do buy new we love to buy and support locally.
