Think you have your wedding budget all planned out and every single expense accounted for? Well, chances are you didn’t plan ahead for the unexpected costs along the way or you were too modest when you guessed how much some of your vendors and decorations would cost you.

Do yourself a pre-wedding favor and revise your budget after seeing how much these common wedding expenses actually cost.

1. When You Dress to Impress
The dress itself will have quite the hefty price tag, especially if you have your eyes set on a designer gown. But you’ll also want to factor in the price for alterations (which can be a couple hundred extra) and accessories for the dress, like a belt, shoes, and veil (which could be close to a thousand dollars more).

2. If You Want it Live
On the top of some couple’s must-have list is a live band at their wedding. A DJ just isn’t their thing and they have their heart set on a 6-piece band with a crew of singers. A band that size can cost anywhere from $10,000 to over $20,000 so be sure to factor that in to your wedding budget.

3. All of Your Vendors
Think you paid all your vendors in full and your done handing over the cash? You’re wrong. You’ll want to tip your vendors, especially if they did a good job and that’ll cost you close to $1,000 more.

4. Food for All
Having good food at your wedding is one of the most important things. Catering appetizers and a main course for your guests, plus bar service and dessert, can run you upwards of $10,000.

5. The To and From
Forgetting something on your pre-wedding to-do list? It’s probably transportation. Plan ahead how you’re going to get to and from your wedding venue or you may have to pay a higher cost on the day-of calling a taxi or arranging a car service.

6. Fresh Roses
Flowers smell good but they also cost a lot of money. Consider skipping fresh flowers everywhere and use an alternative decoration, especially for your centerpieces.

7. Someone to Marry You
Thought you’d find someone for free to lead you into the world of I Do? Having a trained and well-spoken officiant for your wedding can set you back anywhere from $500 to over $2,000.
