Beneath this, breathable fabrics like cotton or light wool are perfect for adapting to the day’s warmth. For footwear, comfortable walking shoes are essential, as the city’s pavements are best explored on foot, and a waterproof pair is always a wise choice given the increasing likelihood of spring showers.
