When even one tree gathers together, it becomes a grove, and eventually a forest. The pajamas depict a tree with animals playing in it, and the design creates a forest when families gather and line up. Just like taking a walk in the forest, families can look for animals together, take photos, and create fun times in their everyday lives. It is loose and comfortable to wear, and has a good texture and moderate thickness, so it can be worn all year round. The kids size has a fully open snap button front for easy putting on and taking off. Siblings, sisters, and friends all wear Matching style, and we all play around together, and the children and the forest grow!
