Fabric & care
GOTS-certified organic cotton, with a little elastane in the stretch styles. Labels are printed into the fabric rather than stitched in, and the dyes are audited as part of the certification.
- Machine wash cold with like colours
- Do not bleach
- Tumble dry low
- Cool iron inside out to protect the print
Size & fit
Cut with room to move rather than to a slim silhouette, so pieces last through a growth spurt instead of one season. If your little one is between two sizes, take the larger one.
Shipping & returns
Stock sits in a US warehouse, so orders ship fast domestically. Shipping is free on orders over $40, and $10 flat below that.
Returns are free within 15 days — we send you a prepaid label. Order two sizes and send one back if you are unsure.
