7 Wedding Planning Mistakes That Can Wreck Your Big Day (And How to Avoid Them)
There’s a very specific kind of heartbreak that comes from realizing you messed something up during your wedding.
Like the... “We paid how much for what??” or “Wait… did we ever file the marriage license?” kind of heartbreak.
And the thing is ... most of these mistakes?
They’re not even your fault.
You’ve never planned a wedding before.
You’re figuring it out as you go.
And half the advice out there feels like it was written by someone’s auntie in 2012.
.
.
.
So let’s fix that.
I pulled together the most common (and lowkey heartbreaking) Wedding Planning Mistakes brides make ...and exactly how to avoid them.
So you can plan with peace and confidence.
Let’s get into it.
1. Booking Your Venue Before Making a Guest List:
I get it.
You fell in love with a gorgeous venue, and you must have it.
But pause.
Breathe.
Have you even counted how many people you’re inviting?
Because nothing kills the wedding vibes faster than realizing you’ve crammed 200+ guests into a space meant for 75, or worse - overpaying for a ballroom when only 50 people actually show up.
Solution: Make a rough guest list first. Not final, not perfect—just enough to know what kind of space you need. Trust me, future you will thank you.
2. Assuming Everyone Reads Your Wedding Website:
Ah, the wedding website.
A beautiful, well-organized hub of critical information.
Unfortunately, half your guests will act like it doesn’t exist.
Some will still text you, “Hey, what’s the dress code?” even though you made a whole page for that.
Solution: Repeat key info in multiple places ...invites, email reminders, even a group chat if necessary.
Basically, assume your guests are adorable but helpless.
3. Choosing a Dress Without Checking How It Moves:
You twirl in the mirror, and it’s perfect.
But did you sit in it?
Did you dance in it?
Because you don’t want to realize, mid-reception, that your dream dress turns into a medieval torture device when you try to bust a move.
Solution: When you try on your dress, do everything in it.
Sit, squat, twirl, maybe even sprint (okay, maybe not sprint, but at least a little wiggle).
4. Forgetting to Eat on the Wedding Day
This is not a joke.
You will forget to eat if you don’t plan for it.
And then, at 7 p.m., you’ll suddenly be lightheaded, hangry, and dangerously close to tackling a waiter for a canapé.
Solution: Assign someone (not you) to make sure you eat.
A bridesmaid, a planner, even your mom.
Somebody needs to shove a sandwich in your face before the ceremony.
Btw... Quick interruption.📢
Just wanted to drop this in real quick:
If you’re planning your wedding without a Wedding planner (aka doing it all themselves).
I made something that’ll help.
It’s called the Wedding Planning Bundle 💍
It’s packed with everything you could possibly think of when it comes to wedding planning
...guest list, budget, vendors, timeline, floor plan, inspo board, checklist... and so much more
So you're not stuck figuring out everything from scratch

5. Trusting That Your DIY Projects Will Be “Quick and Easy”
Oh, my sweet summer child.
No DIY wedding project is quick and easy.
What starts as "I’ll just make some cute table numbers" can spiral into a full-blown craft store meltdown at 2.am the week before the wedding.
Solution: If you’re DIY-ing, set strict deadlines.
And for the love of all things holy, don’t leave it for the last minute.
6. Not Having a “Bathroom Break” Plan for the Dress:
If your dress has a lot going on, you know ....long train, layers of tulle, or a corset situation.
Then you might need a little ....logistical support for bathroom trips.
And by “support,” I mean a bridesmaid or ...maybe two.
Solution: Try using the restroom in your dress before the big day.
Also, Google “bridal bathroom hack.”
You’re welcome.
7. Skipping the “Marriage License” Part of Getting Married:
It’s all fun and games until you realize that, legally, you’re not actually married because you forgot to file the paperwork.
Don’t be that couple.
Solution: Look up your state/country’s marriage license rules early.
Set a reminder to file it.
Remember celebrate after you’re officially hitched.
Final thoughts
Avoiding these mistakes?
That’s how you keep your wedding day from turning into a chaotic sitcom.

...but if you stay ahead of the big pitfalls, you’ll be just fine.
