On our wedding day next year in our Costa Rican with a beach ceremony, my fiancée will be wearing a 'Guayabera' shirt. I'm creating the 'Save the Date,' and I'd like to guide our guests on attire. I’m thinking about leaving it for the actual invitation, but considering putting it on because it’s a destination wedding (?).

I don't want anything more formal than the Guayabera, (specifically for men) but I also want to maintain a certain level of elegance for our beachfront sunset wedding. Considering the hot province and the outdoor setting for both the ceremony and reception, what attire would you recommend for our guests?

I'm considering “cocktail attire” but open to suggestions. Some friends suggested either an all-white dress code or providing a color palette for guests to choose from. What are your thoughts?
