On Wednesday, April 8, 2026, MADISONBLUE will release the "HELLO L/S TEE KIDS," a long-sleeve version of the brand's iconic "HELLO T-shirt." Created with the same proportions as the adult version, the "HELLO L/S TEE KIDS" comes in basic white and cool black, with four sizes (100–130) available, just like the existing short-sleeve model. To be gentle on children's delicate skin, the tags are placed on the outside. It’s perfect for matching outfits with moms, dads, grandmas, and grandpas.

April is a season of "first meetings" for children, such as starting a new school term or beginning new extracurricular activities. Even for shy children, this "HELLO" T-shirt can serve as an icebreaker, naturally starting conversations and helping to bridge communication between kids. This item not only allows children to enjoy wearing it, but also turns these "first meetings" in new environments into successful experiences, helping them discover the joy of connecting with others.

In addition, a portion of the proceeds from the KIDS HELLO T-shirt will be donated to the international NGO Save the Children, which specializes in child support. The donations will be used for activities aimed at creating a society where the rights of children—who carry the future of Japan—are protected, and where they can hold onto hope and fulfill their potential fairly.
