Midi is a medium length in which a skirt or dress ends around mid-calf, between the knee and the ankle. It is the most versatile and elegant of lengths: restrained enough for the office and formal occasions, yet modern and relaxed for everyday. Midi has an interesting quirk — it is arguably trickier than mini or maxi because it crosses the calf at a 'delicate' point, so it needs the right balance with footwear to avoid visually shortening the legs. With heels or boots, midi looks slender and refined. It is a length often called the most 'grown-up' and timeless.
