Charles Tyrwhitt Men's Slim Fit Pure Cotton Twill Shirt - 1634 - White - Available at M&S
When the dress code is business-casual, reach for this shirt by Charles Tyrwhitt. It's cut to a slim fit, with gentle tapering at the waist for a modern look. The minimal, cutaway collar adds a contemporary air, while pleating at the single cuffs lends a little extra room through the sleeves. It feels soft and breathable, thanks to the pure cotton twill fabric.
