Quick Answer
Pack three to four mix-and-match pieces in royal blue and white for the daytime sessions, plus one statement piece for the banquet.
Founded at Howard University on January 16, 1920 by the five women known as the Five Pearls, Zeta Phi Beta built itself on Scholarship, Service, Sisterhood and Finer Womanhood, and remains constitutionally bonded with Phi Beta Sigma. Its colors are royal blue and white, and the Grand Boulé is where the sorority gathers to govern, honor and celebrate.
This guide comes from a house Zetas already choose. When the Zeta Phi Beta Southern Region kicked off its conference, the sorority's International President, Dr. Stacie NC Grant, did it with a "Women Who Win" pop-up at the Sai Sankoh showroom in Dallas. Zeta's International 1st Vice President, Gina Merritt-Epps, wore her white Sai Sankoh Melba at the Grand Boulé. The label was also named Best Resortwear by D Magazine in 2024 and worn by Beyoncé and supermodel Iman.
Let royal blue and white lead, as real clothing, not a uniform. A royal-blue goddess kaftan or a floor-length dress reads beautifully at the banquet. Crisp white and ivory separates are sharp for daytime sessions and photograph clean. A print that carries royal blue is a smart everyday choice for the marketplace and committee days.
Business and plenary sessions ask for wide-leg trousers with a clean blouse, or a fluid dress, block heel, since comfort matters over long hours. The marketplace calls for a shirt dress you can split. The banquet is the dress-up night for a royal-blue goddess kaftan or floor-length dress.
“Keep the line clean and let the blue be the statement.”

Frequently Asked
What should I wear to a Zeta Phi Beta Grand Boulé?−
Pack three to four mix-and-match pieces in royal blue and white for the daytime sessions, plus one statement piece for the banquet.
How do I stay in my colors without looking like a uniform?−
Lead with an original print that carries royal blue and white rather than a flat solid, so it reads as your colors without matching everyone else.
What is the most comfortable option for a full day of sessions?−
A one-size goddess kaftan. It falls from the shoulder, moves with you, and takes you from a morning workshop to an evening reception with only a change of shoe.

Understanding the measurements
1
Length is what matters
Use length to choose between styles — Melba (57”), Mini (23.5” front), Marlo (59.5”). The kaftan will fit.
2
Chest & shoulder are garment dims
Do not compare to your body measurements. The kaftan is intentionally oversized.
