:''The term semi-formal is also used in
formal methods (
computer science) to mean not fully
semantically formalized.''
'Semi-formal' is a
dress code that is analogous to
black tie, and indicates a level of dress between a
lounge suit and
white tie. Traditionally, semi-formal calls for a
dinner jacket in the evening or a
stroller before six o'clock. Women traditionally wear either an
evening gown or a
cocktail dress, depending on the time of day.
In a large part of the
United States since the middle to late
twentieth century, the term "semi-formal" has come to indicate something altogether different in colloquial usage. In many cases this modern American sense of the term semi-formal indicates a level of dress between
business casual and
black tie, and calls for a
suit for men and a
cocktail dress for women. This level of dress is similar to
informal attire in European usage.
Additionally, in parts of the United States, "semi-formal" can also refer to a
high school dance for ninth and tenth graders. While not as formal as
proms, semi-formals require girls to wear dresses and boys to wear suits.
