Start by identifying four factors: fit, sleeve length, fabric blend, and collar style. In Defacto's plain beige range you can pick between relaxed and regular fits, and between short or long sleeves. Choose your fit based on how you wear it: relaxed for casual layering, regular for a cleaner, neater look. Compare fabric blends: 100% lyocell offers softness and drape, while blends (for example cotton-50-lyocell-50 or cotton-41-lyocell-59) add texture or durability. Finally, select the collar style that suits the occasion—plain for a minimalist look or polo for a bit more structure.
