What to pack for a city break? Light, is the main thing.
First up, always check the weather forecast. It sounds obvious but the downside of the duration of a weekend trip is a perk when it comes to packing. If it's set to pour, leave the shorts at home. If it's set to be blazing, scary as it sounds, coats away and a light jacket will suffice.
Where are you going? What will you be doing? Most items can double and even triple up. A good pair of jeans or relaxed tailored trousers will see you through almost anything, as will a well-cut shirt. Throw in a jacket, culottes, a silk t-shirt and dress, you've got yourself a fair few outfits to mix and match. As for shoes, one flat pair you can walk around in, like a sneaker or sandal (if it'll definitely be sunny. Toes out in the rain is a no-no). And an optional pair of heels. Make them an on-trend midi to be on the safe side.
