C-Theory Collection
The C-Theory collection takes cues from color theory in fashion and art—where contrast and balance are used with intention. Solid, saturated fabric colors are paired with contrasting elastic details to create a bold look that feels deliberate, not loud.
Built on a textured cotton stretch fabric, C-Theory delivers everyday comfort with visual impact. It’s confident color, refined through proportion and contrast, designed to stand out without feeling overworked.
Model's height is 6"1'/185 cm, and he is wearing size M.
