A city on foot, for nine hours
Chosen for a day of walking, queuing, carrying and being in other people’s photographs.
Built on: Comfortable shoes and layers, because you will be too hot and too cold on the same day.
A day of sightseeing is physically closer to a hike than to a day out, and the accessories that work reflect that. Nine hours on your feet, a bag on your body the whole time, weather changing, and a lot of standing still in queues.
The bag is the entire decision and there are two real requirements. It must close properly — a zip, not a magnetic flap — because crowded tourist areas are where bags get opened, and an open tote in a packed square is an invitation. And it must be worn across the body rather than on one shoulder, because nine hours of single-shoulder weight is a genuine backache, and because a crossbody cannot be lifted off.
Weight distribution matters more than capacity. A small bag worn tight to the body is more comfortable at hour eight than a large one carrying the same things loosely. Everything you are tempted to bring "just in case" you will carry for nine hours.
Sun protection is the thing most people underestimate on a city break, because it does not feel like being outdoors in the way a beach does — but you are outside all day, often on reflective pavement. A brim and UV400 lenses do more than sunscreen at the top of the face.
Jewellery: minimal and cheap. Not because of theft specifically, but because hot days, sunscreen and constant movement are hard on it, and because anything you are consciously protecting is a distraction from the thing you travelled to see.
The one indulgence worth allowing is a bag charm. It is the accessory equivalent of a fridge magnet, it costs almost nothing, and it makes an identical black crossbody findable in a hostel dorm or a cloakroom.
