This men's slim-fit long-sleeve shirt is your go-to choice for smart casual occasions in autumn and winter, weekend outings, and relaxed office days. Cut with a tailored silhouette that flatters without restricting movement, it pairs effortlessly with chinos, jeans, or trousers for a polished look through the Christmas party season.

Why You'll Love It

  • Tailored Slim Fit: A shaped silhouette that flatters the body while allowing a full range of movement throughout the day.
  • Chest Pocket Detail: A neat chest pocket adds a classic, structured finish to the clean front placket.
  • Versatile Smart Casual Style: Clean lines and a spread collar make this shirt equally suited to the office or a relaxed weekend setting.

Perfect For

Wear it tucked into slim-fit chinos for a smart office look, or leave it untucked over dark jeans for a weekend coffee run. It also works well under a blazer for smart casual evenings out, such as the office Christmas party, or layered beneath a wool coat on colder days.

Care Instructions

  • Machine wash at 30°C on a gentle cycle.
  • Do not bleach.
  • Tumble dry on a low heat setting or hang to dry.
  • Cool iron if needed, avoiding any printed areas.
