What to Do 3 Months Before Your Wedding (The Calm, Detailed Checklist)
If you're three months out, it can suddenly feel like everything is happening at once.
Take a breath.
Most of the big decisions are already done. Your venue is booked, your key vendors are confirmed, and your date is set. These final 12 weeks are about refining the details, keeping communication simple, and making sure everything runs smoothly.
If you're planning your entire wedding within three months, review the earlier stages first: our 12 Month Wedding Planning Checklist, 9 Month Wedding Planning Checklist, and 6 Month Wedding Planning Checklist. Otherwise, use this as your structured guide to the final stretch.
The key is to break it into small tasks and spread them across the next 12 weeks. No overwhelm required.
Wedding Attire
If your dress or custom pieces were ordered months ago, the final three months typically include fittings and finishing touches:
- First fitting when your dress arrives
- Alteration fitting
- Final fitting around 3 to 4 weeks before the wedding
Things to finalise now:
- Confirm bridal party attire delivery dates
- Buy wedding shoes before your final fitting
- Choose your veil or headpiece
- Finalise jewellery and accessories
- Select and order your wedding bands
- Choose a rehearsal dinner outfit
- Start a honeymoon packing list so nothing is forgotten
If you're buying off-the-rack or second-hand and haven't yet, do it immediately to allow time for alterations.
For grooms: confirm suit fittings and shoes now. Last-minute suit shopping adds stress and limits options. If you're preparing the groom’s speech, this is also an ideal time to start drafting.
If you want one place to track fittings, receipts, and what still needs ordering, our Little White Book wedding planner keeps everything together.
Send Wedding Invitations
At three months out, your formal wedding invitations should be sent.
Set your RSVP deadline for around 4 weeks before the wedding so you have time to confirm numbers with your venue and caterer, and finalise your seating plan.
Practical tips:
- Weigh a fully assembled invitation at the post office before stamping everything
- Double-check postage for thicker or wax-sealed envelopes
- Request hand-cancelling if you want a cleaner finish
If you're using digital invitations, be consistent with follow-ups and track responses carefully.
Also worth ordering now: a beautiful wedding guest book, so it arrives well before the day.
Apply for Your Marriage Licence
You can apply for your marriage licence between 3 days and 3 months before your wedding.
Do not leave this until the final week.
Confirm the legal requirements for your country and make sure:
- Names are correct and match your ID
- Your celebrant details are accurate
- Your venue and date are correctly listed

Finalise Vows and Speeches
Do not leave vows to the final week. Give yourselves time to write something you truly mean.
In the next three months:
- Begin drafting vows in small sessions
- Meet with your celebrant to confirm ceremony structure
- Choose readings and confirm who will read them
- Ask speakers to start preparing early
If you're writing a speech to your partner, our guide on how to write a wedding speech can help. The groom should also start shaping his wedding toast.
Your Little White Book wedding planner includes “Our Love Story” pages that make vow writing easier, because the best words come from real memories.
Hair, Makeup and Beauty
If you're using professionals, confirm:
- Your bookings and start times
- Trials for hair and makeup
- Bridal party numbers and timings
Now is also the time to:
- Focus on consistency with skincare
- Hydrate properly
- Book facials (not too close to the wedding)
- Avoid brand new treatments or major changes
Consistency is better than experimentation.
Catering and Cake
Three months out is when you should:
- Finalise menu selections
- Confirm dietary requirements
- Confirm beverage packages or quantities
- Order alcohol early if your venue is BYO
- Finalise cake flavours and design
- Purchase your cake topper (if using one)
If you're considering a modern catering option that feels abundant and relaxed, explore our guide to grazing tables for wedding catering.
It’s also a good moment to review your numbers so catering choices stay aligned with your overall spend. This real example helps: Actual Wedding Budget Breakdown.
Honeymoon Admin
Before wedding-week chaos begins:
- Check passport expiry dates
- Book flights in your passport name
- Buy travel insurance
- Confirm accommodation
- Check visa or ESTA requirements if travelling overseas
Avoid unofficial visa websites. Always apply through official government channels.
Hens, Bachelor and Pre-Wedding Events
Your bridal party will often lead this, but you can help by:
- Providing guest lists
- Confirming dates that work around key wedding appointments
- Sending thank you messages for any shower gifts
- Confirming wedding night accommodation
If you’re hosting or attending a bridal shower, our beginner’s guide to planning a bridal shower is a helpful starting point.
Confirm Wedding Night Accommodation
Even if your venue includes accommodation, confirm:
- Check-in details
- Key collection
- Transport after the reception
- Any special requests
You’ll be grateful for a calm retreat after the celebration.
Keep Your Diary Updated
The final three months can blur. Keep notes on:
- Emotions and milestones
- Small wins and funny moments
- Unexpected hiccups you’ll laugh about later
You will never regret documenting this season.
Final Reminder
The last three months are not about perfection. They’re about coordination.
If something is not exactly as imagined, it will not define your wedding.
The most important work is already done.
