Start with what you are wearing. Go ahead and be bold with a kilt, decorative pin or sari. Next decide on the traditions you want to incorporate like jumping the broom, walking on a bed of flowers, even the money dance!
Another easy way to mix in your culture and heritage is with food! Go all out serving authentic cuisine to your guests. They will absolutely love the cultural flare you added.
Top it off in a way that not only looks gorgeous but smells amazing, too — with flowers! Decorate everything from the bouquets and boutonnieres to the ceremony and reception with flowers that are meaningful to the culture or heritage you are celebrating.
