Seishun — meaning Youth in Japanese — is a premium streetwear label for children and teens aged 6 to 16, founded by sibling trio Griva Shah, Sahil Rathod, and Tanish Rathod.

 With a 60-year old family legacy in textiles, craftsmanship and quality runs in our blood.

Born from a deep-rooted passion for fabrics and an evolving love for fashion, we’ve reimagined kidswear with high-quality materials, custom prints, and modern designs that capture the fearless spirit of Gen Z and Gen Alpha.

At Seishun, we believe youth is not just an age — it’s an attitude. A bold, expressive, and unapologetic vibe that deserves to be worn with pride. Our collections celebrate individuality, creativity, and the confidence to stand out.

Because cool is in your DNA.
