Here are a few suggestions that you might use. Call your venue and see what they can do for you. Maybe a new date or if that date is taken maybe you can get a refund if you can't come to an agreement. Most venues will work with you. If a bride and her bridesmaids already have their dresses and don't want to go through the expense of ordering different gowns because the date was change to a different month try this. Consider using flowers that bloom in that month in your bouquet. Once you set a date call all your other vendors and see if they can change the date for you. Hopefully they will be able to, but if not maybe they can suggest someone to help you.
