Don’t let a destination wedding come between you and your dream dress. I’ve seen brides successfully get married in Costa Rica in everything from simple sundresses to full-on ballgown style gowns. Simple dresses with slim silhouettes are the easiest dresses to travel with, but again don’t let that stand in your way. If you choose a fabric that doesn’t wrinkle easy, you can fold your dress up carefully and stow it in your carryon. This is the easiest/cheapest option. If you’re worried about wrinkles, bring your dress as a carry-on in a garment bag. Some planes will have a closet in first-class where you can hang the dress. If not, wait until a bin is full and then lay your dress out on top of the bags.  If you have a large, poofy dress and/or are really concerned about it arriving in perfect condition, you can always buy the seat next to you and give the dress its own space to rest.
