Case Study: 3Claps achieves 50% month-over-month growth with Shopify Plus

How a South Korean Entrepreneur Uses Homemade Cookies to Grow a Little Girl’s Fashion Brand 50% Every Month

3Claps is a special-occasion fashion brand for little girls founded by MJ Kim. Facing steep U.S. pricing in the market, limited funds after earlier failures, and the need to prove his concept with only one remaining sample, Kim needed a way to attract attention and validate demand quickly.

He sent that final dress paired with custom cookies to a top children’s fashion influencer, sparking social buzz and rapid demand. Kim then leveraged South Korean family-run manufacturers for affordable, high-quality product and upgraded to Shopify Plus to scale—achieving roughly 50% month-over-month growth, a faster, more integrated site, strong social proof, and 35% of purchases coming from repeat customers.
