Just as with any big show, your wedding day will not be perfect - but that's okay. While you cannot plan ahead for every little detail or problematic situation that may arise, you can arm yourself with some helpful advice to be prepared at all times for any potential wedding mistakes. But before you begin planning your special day, consider these five biggest wedding preparation and planning mistakes that amateur 'wedding planners' often make.

1. Not Budgeting Costs
 
It's hard to believe, but true - many couples do not create a budget when it comes to wedding preparation and end up in a deep hole of debt. The very first thing you should do to avoid disastrous (and bankrupting) wedding mistakes is devise an itemized budget, allowing for the necessary requirements, such as a venue for both the ceremony and reception, food and drinks, flowers, favors, decorations, etc. If anything is left over, either use this money for your honeymoon or spend it on something a little more frivolous, like a horse drawn carriage for your departure from the reception. Budgeting ahead of time also involves your acknowledging the fact that you may surpass the total by at least 10%. Surprises do happen, so cutting back on other needless things will ensure that you don't go over budget too much. In these initial wedding preparation stages, you and your fiancé need to discuss who will be paying for what. It used to be that the bride's parents paid for everything, but this ideal is slowly fading away. If you're still coming up short on funds, there are literally hundreds of ways to cut costs for your wedding day, including having fewer guests, choosing an off-season date, selecting flowers that are in season, and having friends and family play a bigger part by making the wedding cake or trying their hand at photography.

2. Not Giving Yourself Enough Time

The image of the harried bride has been engrained into the psyche through a number of television shows that hype up the combination of little to no time and a 'my way or the highway' attitude. This is why giving yourself ample wedding preparation time is necessary to ensuring that your wedding flows seamlessly. If you want a large, extravagant wedding, you need to begin planning at least a year and a half in advance; for a smaller, more intimate wedding of about 50 guests, eight months to a year is fine. You need to take into account what your plans are for your wedding and adjust your schedule accordingly to prevent costly wedding mistakes from occurring. Giving yourself more wedding preparation time allows you to order your cake, dress, wedding favors, flowers, decorations, etc. well in advance so that you don't come up empty-handed from last minute rushing. Allotting enough time also applies to your wedding ceremony and reception. Don't keep your guests waiting at the reception venue while you and your wedding party are taking hundreds of photos - consider taking a majority of the pictures before the ceremony and the all-important couple, wedding party, and family pictures after the vows have been exchanged.
