Business Formal

For the Executives
The dress code suggestion at many daytime semi-formal events (particularly work lunches and conferences), this dress code calls for a suit and tie for the guys and a tailored dress or a pantsuit for women. The idea is to wear something business appropriate, that also feels dressed up.
