Siaomimi is created by Hilda Yim. Hilda was graduated from Parsons School of Design in 1992. She had worked for Anna Sui and DKNY before she decided to move back to Hong Kong. In 1995, she introduced her own womenswear label Shopaholic and Yim and was represented in New York. More than 70 stores all over New York, San Francisco, Los Angeles, and Tokyo have brought her collections. They were being sold through leading upscale specialty stores and department store like Barneys New York, Steven Alan, American Rag and Spick and Span in Tokyo, etc.

In 2006, Hilda gave birth to her daughter, Charisse, who has a nickname "Siaomimi". Siaomimi was given her first Chinese nanny who couldn't pronouce Charisse properly. Everyone loves the sound of Siaomimi and has been calling her that ever since.

Hilda became so inspired by the whole experience and she couldn't wait to start designing childrenswear. Her collection reveals the quality of children's innocence and simplicity, but yet with strond individual character. All the prints are inspired by her childhood memories and are all exclusively hand block printed for the collection. She also loves creating nice subtle details in her designs, like applying handmade or crafty work. Quality is also very important to the collection, only the finest cotton or cotton cashmere are being used.
