 About The Fabric 

Japanese Dyed Gabardine. 95% cotton 5% Polyurethane. Piece-dyed. The fabric contains a slight amount of stretch for extra comfort.

Styling Advise

This stylish blue suit makes a statement. The toned-down hues of the check make it easily matched with another spur of colour – yellow is a good choice as it makes the subtle beige in the check pop. Try our slim fit shirt with a shoulder strip in yellow or for a fully colour coordinated outfit the slim fit shirt with pleated back in navy. Both great choices especially when you leave the jacket behind.
