This wedding dress is perfect for your special day. To put it on, step into the dress and carefully pull it up over your body. Make sure the spaghetti straps are properly placed on your shoulders. As for sizing, if you've ordered a custom size, double - check your measurements before sending them to us. When it comes to maintenance, store the dress in a cool, dry place away from direct sunlight. Avoid hanging it for long periods to prevent stretching. If it gets dirty, it's best to take it to a professional cleaner who has experience with organza and lace materials. Enjoy your beautiful day in this wonderful dress!
