Sizing, care, and shipping for our Baby T-Shirts — quick answers for parents.

How do I choose the right size for Lūmmi in Colour Baby Boy Clothes?

We recommend checking our detailed Size Guide to find the best fit. Our Baby T-Shirts are generally true to size. If your child is between sizes, we suggest sizing up for comfort and longer wear.

Are these Baby T-Shirts suitable for sensitive skin?

What is the best way to wash and care for Baby T-Shirts?

Wash on a gentle cold machine cycle with mild, baby-friendly detergent. Avoid harsh chemicals or bleach, and dry in the shade to help preserve softness and colour.
