Spring cocktail attire in vibrant seasonal colors is perfect! For the ladies, midi dresses or dressy separates in florals or bold spring hues are welcome. For the men, a suit or slacks with a blazer works great—ties optional. We’ve included a mood board for inspiration, but feel free to wear whatever feels fun and true to you—just please avoid all white, pastel blue, and dark brown, which are reserved for the bridal party.
