R&D

We have assembled a professional R&D team consisting of children's wear designers, pattern engineers, fabric development and process specialists. We are deeply engaged in the research of children's ergonomics, familiar with domestic GB 31701 and European and American children's wear safety standards, and strictly adhere to the Class A safety standards for infants and children.

Style Development: 1000+ new styles per month/year

Following the latest children's clothing trends, we independently develop patterns, designs, and color schemes; while also considering practicality (durable, easy to put on and take off, protects the belly, and allows for freedom of movement), we cater to the needs of influencers across all platforms.

1000+ monthly/annual averageTrend Analysis & Independent Product Development

• A multi-year children's library

Relying on the children's clothing version database that has been precipitated for many years, the version is independently opened for the growth characteristics of children of different ages; the shoulder line, crotch, elasticity, and shoulder drop are optimized to solve the pain points of running, jumping, bending, and sitting for a long time, and the version is tried on for multiple rounds.
