6 Ways You May Be Sabotaging Your Wedding

1. You don't stick with your budget. Simply put, you have a budget for a reason. Early on, prioritize what you want to splurge on and what you want to save on. For example, do you care more about the flowers or the photography? When you have an idea of how high you're willing to go in each of the main categories, it'll be easier for you to narrow down your vendors and negotiate exactly what you're getting. 
2. You plan your own bridal shower and/or bachelorette party. Let your mom, aunt, maid of honor, best friend or anyone else plan these two events. It's okay to give particular guidelines (like no strippers), but you shouldn't book any hotel rooms or create a detailed itinerary. Your friends will have lots of fun planning it, and you'll be better off since you'll have more time to focus on planning the main event. 
3. You choose to do your own hair, makeup and/or flowers. Although you might be able to make your own favors or print your own menus, there are particular aspects of your wedding you should leave to the professionals -- hair, makeup and flowers are generally at the top of the list. Having your hair and makeup done professionally ensures you'll look amazing from beginning to end. And there won't be enough time for you to do every single centerpiece, bouquet and boutonniere yourself.
4. You don't have a Plan B for an outdoor wedding. Always ask about rain when you're visiting potential venues, even before you book. By doing this, you're guaranteed to get something you're equally happy about, no matter what the weather does. Also, think about other weather conditions: Get heat lamps if you're planning your wedding for early fall, and provide paper fans just in case you have an extra sunny summer wedding.
5. You wait until the big day to try on your shoes. Yes, you want to keep your fabulous shoes in perfect condition, but you should try wearing them around your house, at least, for several hours on a few different days before your wedding so you can avoid blisters or pinched toes. Even if you plan to change shoes after the ceremony, you want to be sure you can both comfortably and confidently walk down the aisle in your heels.
6. You assume you'll be coordinating the day-of. The only thing you should have to do on your wedding day is enjoy yourself. You've likely heard this many times before, but the day goes by very quickly. If issues pop up that can't be handled beforehand, try to hand them off to your mom, maid of honor or a helpful family friend to deal with. Even better: Consider hiring a day-of coordinator to be certain everything runs smoothly.
