Semi-Formal or After Five means that tuxes are not required, nor are long dresses, but you should still look fierce!

Men: An evening wedding (after 6 PM) would still dictate dark suits for him, however for an event during the day, lighter colored suits are not only appropriate, but appreciated.

Women: Combine the class of Jackie O with a little edge and you will be sure to make the girls jealous and the boys swoon. Form-fitting cocktail dresses are a staple for semi-formal attire. For a fail-proof daytime semi-formal, an appropriate short dress or dressy suit should work. Business Formal is the same as Semi-Formal for him, but for women it suggests that women opt for more tailored dressy suits and dresses (nothing too slinky or sexy).
