In Western clothing, Semi-formal is a grouping of dress codes, indicating the sort of clothes worn to events with a level of formality between informal (i.e. lounge suit) and formal. Historically there were both day and evening semi-formal dress codes, but this category is now seen almost exclusively in the context of evening wear.
