Hermes Kelly Mini 2424 24/24 Bag 21CM Handmade In Evercolor and Swift Calfskin Leather Silver Hardware 73 Blue Saphir

Same sapphire as its gold counterpart, dressed for daylight instead. Where that version leans warm and evening-ready, the silver hardware keeps this blue cool, clean and slightly architectural, the colour of deep water in the morning rather than candlelight. If you own camel and cream, both versions have a place; if you own mostly navy, this is the one that speaks your language.

Twenty-one centimetres in width and sixteen in height, Evercolor and Swift as usual, with the fittings staying almost invisible against the dark blue. What I like most is the strap hardware: small, flat and quiet enough that the bag never jingles when I set it down.

Phone, keys, two cards and a tissue pouch live in it on office days, and the blue is dark enough that it reads professional in a meeting while still being a colour at all, which is a balance I chase in vain with most bags. The strap also survives being shoved into a tote without tangling, which sounds minor until you have unwound a knotted chain at an airport gate.

An honest tip: this cool sapphire can look flat under warm indoor bulbs, where it shades toward black. Decide based on the light you actually live in. Outdoors, and in any room with a window, it is superb; I plan my wear accordingly and have no regrets.

If your wardrobe runs on navy, grey and white, this is the blue that will make it look deliberate rather than accidental.
