Midi dresses are the most versatile length going and we will not be taking questions on this. Below the knee, above the ankle. Works in summer with sandals, in winter with boots and tights, at the office with heels, at the weekend with trainers. The midi length flatters almost universally and it works across so many occasions that owning several is entirely justified. These are our current favourite midi dresses across every style. The ones genuinely earning their wardrobe space right now.
