When your dress arrives:
Take the dress home in a long garment bag preferably laying it along the back seat or even hooked from its hanger at one window and then along the seat. The gown should then be hung somewhere high so any creases can drop out.
Leading up to the wedding:
When you get the gown home don’t constantly try it on or pull it out of the bag and show people. The more you handle liquid silk and delicate fabrics the more oils can mark the fabric and over time the marks will become worse.
On the day:
Keep in mind not to hang the gown from a fire sprinkler system on the ceiling of your hotel room. Make sure you hang it from a cloths hook and that the hook will be able to sustain the weight of your wedding dress. Do not let any bridesmaids hands fall upon your gown the night before … and remember pack a scarf with you, so that when you put your dress on make-up will not smudge on your dress.
After the wedding:
Make sure you get your dress cleaned by a reputable dry cleaner.
