A destination wedding requires getting your dress there one way or another. If you don't want to pack it in your luggage -- or won't have space -- ship it ahead of time to meet you there. It can be nerve-wracking to let your precious dress out of your sight, but with a little attention to how it's packed, it will arrive safely and in beautiful condition.
Start with a large and sturdy corrugated cardboard box. Line the box with tissue paper, then place the gown face down and centered on the box. Arrange about a third of the dress above the box and a third below. Spread it out as flat as possible to avoid wrinkles. Place some bunched tissue on the skirt portion and fold over the skirt lengthwise until the folded skirt is no wider than the box. Fold the skirt up into the box; add a layer of tissue; then fold the top of the dress into the box. Ideally, your dress will fill up most of the space in the box without crowding. Add extra crumpled tissue to fill any extra space.
Once you've properly packed your wedding dress, tape each seam of the box with sturdy packing tape. Place the shipping label on top. Make sure that the destination address is clearly printed in permanent ink. Cover the address with a layer of transparent packing tape for extra measure, and don't forget to include a return address. Place a duplicate mailing label inside the box in case something happens to the outside of the container. Insure the package and ship it using a service that can be tracked. When you again lay your eyes on your beautiful dress, be prepared to remove wrinkles with a hand steamer or in a steamy shower. You may want to hire a professional presser for the job.
