Wedding planner and friend Marcy Blum Associates collaborated with the men to design the evening's festivities. The invites were done by Elum Designs for Sugar Press. The décor combined their color palette of black, whites and creams and included gold touches, and natural elements like geodes and minerals, mixed in with lush greenery.
