Tess Nguyen, a first-generation Australian from Vietnamese immigrants, transformed a modest $15,000 Gumtree purchase of a pajama business into Midnight Mischief, a multimillion-dollar fashion brand. Despite her background as a physiotherapist, she leveraged her parents' sewing trade influence and self-taught design skills to expand from four basic pajama designs to a comprehensive sleepwear line for women, men, kids, and bridal parties. Her success stems from strategic influencer marketing, continuous learning, and adaptability. Beyond business achievements, Tess's journey from healthcare professional to successful entrepreneur serves as an inspiration, particularly to those from immigrant backgrounds, demonstrating how determination and strategic thinking can transform modest beginnings into significant success.
