A midi dress with short sleeves bridges summer practicality and the formality that the occasion requires. The sleeve covers the upper arm without making you overheat which is a real consideration in warm weather. Midi length is longer than knee and that extra length adds formality automatically. Black is the straightforward choice but dark navy and deep charcoal work well in summer months. The fabric should be cotton or a cotton blend that breathes. A simple neckline and minimal detail keep the focus on the respectfulness of your choice rather than any style moment. These are the midi dresses that acknowledge both the season and the occasion.
