Heidi Chanel Classic Flap Replica Mini, Black Caviar

Twenty centimetres wide and 12.5 tall, cut as a rectangle rather than the squarer mini most people picture. That proportion is the whole point: it takes a phone lengthways, which the square mini cannot do, and it sits flatter against the body because of it.

• 20 x 12.5 x 7 cm, the rectangular mini rather than the square one.
• Caviar leather — the pebbled grain that resists scuffing, so it survives being set down on a bar or a desk.
• Silver hardware against black, the cooler of the two classic pairings.
• 7cm of depth means a phone, cards and a lipstick sit together rather than competing.

This is the size for an evening where you want your hands free and nothing more than the essentials. Worn on the long chain it crosses the body; doubled up it sits neatly at the shoulder with a coat. Heidi carries the Classic Flap from this mini up to the 33cm maxi, so the jump between sizes can be judged before choosing.
