Even the smartest, most on-top-of-things couple can make mistakes     during wedding planning. Here are the 10 things you should keep     an eye on before saying I do.      
1. Blowing off your budget
It costs a lot of money to put on a wedding. Many excited     brides start booking vendors and making purchases without having     a real budget, and then they're shocked to discover they've spent     all of their money (or their parents' money) and still don't     have half the things they need. If you bounce checks, don't have     the money to pay your deposits, or make your final payments past     your vendors' deadlines, your wedding will not happen as you     have planned. The flowers won't be delivered, your cake will     not be decorated, and the band will not play all night -- unless     you pay up. Planning a wedding is serious business. Make a budget     and keep track of your expenditures.
2. Ordering the wedding gown and/or bridesmaid dresses     late
If going for a traditional bridal gown, brides need to place     their orders six to eight months before their weddings. Most     gowns are made to order; if you wait too long before your wedding     date to make your selection, the gown simply may not be ready     in time. Bridesmaid dresses should also be decided upon during     the same time period, but only after the gown has been selected.     You want to make sure your ladies have enough time to get measured     and find accessories.
3. Procrastinating on that prenuptial...
It is a reality these days that people -- even brides -- have     assets they want to protect. (This is particularly prevalent     now that there are so many second marriages where a bride or     groom may have children to whom they want their assets to go     in case of death.) Leaving the discussion of a prenuptial agreement     until the week before the wedding is a sure-fire way to increase     the stress level by ten thousand percent -- and endanger the     impending marriage. So deal with this potentially sticky issue     months in advance (Zawaj.com     Editor: this applies equally to any provision that the groom     or bride may want to include in the marriage contract).
4. Messing up the marriage license
There are so many rules around marriage licenses that brides     are bound to make mistakes. Be sure to investigate time restrictions     well in advance of your wedding date. Get your license 31 days     before in some states -- and you won't be able to legally marry     on your wedding day because it may be valid for only 30 days.     Go for your license the day before your wedding and you may not     get it in time, because some states have a 48-hour waiting period.     Another common mess-up if you're remarrying is not having official     divorce papers in time to get the certificate.
5. Booking guest hotel rooms too late
Brides often leave blocking out hotel rooms for out-of-town     guests until the last minute. If you're marrying in a city (particularly     one where conventions take place) or in a resort town and you     don't investigate hotel availability in advance, you can literally     end up with not a single room for any of your guests to stay     in. Your wedding might go on -- but no one will be able to attend.     Reserve a room block as early as possible, up to a year in advance.
6. Inviting too many guests
Make sure your guest list and your reception site match numbers-wise.     You can't invite 400 people assuming only 250 will RSVP with     a yes -- because if 300 happen to say yes, you may have to turn     50 away at the door. Sites can't just add 10 more tables, as     fire laws limit the maximum number of people in any room at one     time. To avoid this, assume eighty percent will respond yes and     limit your guest list accordingly.
7. Last-minute beauty blunders
Many brides think that scheduling chemical peels the week     before their weddings will leave their skin looking angelic on     their big days. Others think having their teeth bleached within     days of their weddings will leave those pearly whites sparkling.     Thinking of tanning the day before your wedding? Think again:     You may end up with blisters instead of sun-kissed skin. Last-minute     beauty treatments can lead to breakouts, mistakes, or -- even     worse -- serious infections. Start a long-term beauty regimen     months before the big day and focus on natural and common-sense     measures such as eating a healthy diet and exercising, or you     could risk ruining all the hard work you've done to make your     wedding -- and photos -- perfect. (Never mind putting your health     and happiness at risk for the most important day of your life.)
8. Underpaying postage on invites
You'd be surprised how many brides just stick a stamp on their     invites and drop them in a letterbox. All but a few wedding invitations     require additional postage. The postal service will not take     pity on you -- your invites will be returned (and rubber-stamped     with that ugly "insufficient postage" message) -- and     it will take at least two weeks (never mind the additional $$)     to get them back out the door. Be sure to get one complete invitation     weighed at the post office before purchasing all your stamps.
9. Ignoring religious restrictions
If you plan on marrying in a house of worship, you need to     abide by the rules. Wearing inappropriate attire or not completing     pre-wedding requirements is grounds for your officiant to stop     your wedding before it begins. As soon as you get engaged, be     sure to contact your house of worship to find out about any potential     issues. Some houses of worship won't let you marry on certain     holy dates; make sure to check your wedding date with your officiant     before putting down any deposits for your reception site or vendors.
10. Ignoring weather warnings
Brides marrying outdoors often test fate and just wish for     the best when it comes to bad weather. Always have a backup plan     -- you may not have a place to marry at all, or your guests (and     you) may be in misery at the hands of Mother Nature. Temperatures     normally around the balmy 70-degree mark may unexpectedly turn     into a boiling 100-degree debacle; be sure to have outdoor air-conditioning.     A hurricane, flashflood, or gale force winds may visit on your     wedding day; make sure you have an interior alternative or a     tent as a back-up location.
