Navy Cotton Linen Formal Trouser


Only 2 pieces in stock!

Another upgraded version of SIRPLUS formalwear classics. Crafted in England from our seasonal linen-cotton blend, these navy formal trousers are as breathable as they are durable. Cut with a medium rise, they have a slightly tapered leg, side adjuster buckles for extra comfort, brace buttons, two button-up back pockets and even a ring pocket. They are sold with a longer unfinished hem to pin to your exact length (at either one of our stores or with your local tailor). A formal occasion staple, best worn with a linen grandad shirt and its matching blazer or Nehru jacket.
