There is nothing quite like a crisp linen shirt when the temperature actually decides to climb in London, or when you are packing for a weekend away. This one comes in a classic blue and white stripe that feels instantly fresh. The 100% linen fabric has that characteristic textured handle that only gets softer and more comfortable the more you wear and wash it. The cut is Ralph's Custom Fit, which strikes a clever middle ground. It gives you enough room through the shoulders to move easily, but shapes in slightly at the waist so you do not look like you are wearing a sail. It is finished with a classic button-down point collar and the unmistakable embroidered pony on the chest. Throw it on unbuttoned over a white tee for pub gardens, or button it up with light chinos for an easygoing dinner. It is the kind of piece that looks best when it is slightly rumpled, so do not worry too much about the iron.
