Dressed-up Casual (a.k.a. smart casual): What you wear to evening office functions that don't require a suit, cocktail dress or other formal business attire. For men, a navy blue blazer with gray or tan pants are standard — you don't necessarily need a tie. Silk or banded collar shirts without a jacket are appropriate too. For women, jumpers, palazzo pants with matching or well coordinated tops work well. A black pant suit that can be dressed up or down is always a good investment for professional women, especially those who attend these events regularly
