The 61S Campaign: Shirts for every Body
After years of research and in-depth body size data analysis, DETERMINANT has developed 61 unique size combinations of dress shirts — crafted to suit the diverse body types of Asian men.
In our latest 61S Campaign, we spotlight three remarkable individuals — Jonathan Chua, Paul Foster, and Josephus Tan — each defining success on their own terms.
From overcoming challenges to celebrating milestones, one thing unites them: the timeless white shirt.
Crafted for every BODY. Perfected in 61 Sizes.
Josephus Tan | Lawyer
For Josephus Tan, success comes from purpose. Rising from a troubled past, he dedicated his life to defending those who can’t stand on their own. The toughest moments in his work are emotional, not financial, but they strengthen his commitment to justice and second chances.
Jonathan Chua | CEO
Jonathan Chua believes success is about impact, not noise. But his path hasn’t been easy — bills piled up, partnerships fell through, and businesses failed - these tough setbacks taught him resilience and transformed doubt into discipline. Today, he builds platforms that give communities a voice and inspire real change.
Paul Foster | Actor & Host
Paul Foster once tied success to recognition, until a heart condition reshaped everything. With a renewed outlook, he now prioritizes health and meaningful work. DETERMINANT’s 61S system reflects that same intention — shirts made for every body, allowing him to live his values and celebrate success with confidence.
