3-month checklist
Twelve weeks. One wedding. Here's how.
At three months, Posy switches to weekly buckets. The plan begins with a calming reminder that short runways force clarity — you'll skip a few nice-to-haves and gain a wedding that's exactly the size it should be.
The three-month mindset shift
A long engagement invites decision paralysis; a short one prevents it. You won't visit three venues — you'll visit two and pick one. You won't try ten dresses — you'll try five. This is a feature, not a bug. Short-timeline weddings are consistently rated as calmer and more personal by the couples who plan them.
The rules that keep it calm
Rule one: no save-the-dates. Rule two: no engagement photos. Rule three: fewer than 80 guests unless you already have the venue. Rule four: use a caterer that includes rentals — rebooking rentals separately eats a week you don't have.
Your twelve weeks, week by week
Below is the real Posy plan for a wedding twelve weeks out. Notice the "take a breath" task at week twelve — it's real, and it's there because you need it before you start.

Set the vision together
Before spreadsheets, spend an evening picking three words for the wedding you want — intimate, garden, loud, elegant, whatever fits. Every later decision gets easier when you can hold it up against those words.
Set your total budget and who contributes
Decide the number you're comfortable spending, and have the awkward-lovely conversations with anyone contributing. A written total now prevents a hundred small arguments later.
Draft a guest count range
You don't need names yet — just a low and a high number. Almost every other decision (venue size, catering cost, invitation quantity) hangs off this range.
Choose a date or date window
Pick a season and a few candidate weekends. Holding a range instead of one date keeps venue options open when you start touring.

Shortlist caterers
Ask for a quote based on your actual guest range, including staff, rentals, and service charge. The 'per plate' number always grows once those are added.
Book the caterer
Confirm the menu-tasting date now and lock any dietary flexibility (vegan, kids, allergies) into the contract. A good caterer welcomes the questions.
Plan the bar
Beer + wine + one signature cocktail is a lovely, calm way to serve most weddings. Decide who supplies alcohol (you or the caterer) — it changes the budget a lot.
Start attire research
Try a few silhouettes on before you fall for one online. Bring a friend who tells the truth kindly.

Order invitations
Proof every line twice — dates, times, addresses, RSVP deadline. Order a few extras for keepsakes and forgotten cousins.
Do the menu tasting
Bring notes and a partner opinion — you'll forget which sauce was which by tomorrow. Confirm any last swaps in writing.
Plan the rehearsal dinner
Traditionally the night before, for wedding party and out-of-town family. A private room at a good restaurant is more than enough.
Book the honeymoon
Even if it's a long weekend two weeks after — book something. You will need a soft landing.

Send final headcount to caterer and venue
This number is usually locked 7–10 days out. Add a small buffer for last-minute yeses if your contract allows.
Finalize the seating chart
Print two copies for the venue and one for the coordinator. Any last-minute swaps happen on printed sticky notes, not in the head.
Break in your shoes
Wear them around the house for a couple hours a day, with socks. Blister prevention starts now, not in the ceremony line.
Finish and print your vows
Print two copies each, in a large readable font. One for you, one held by your best person as backup.

Send thank-you notes
Handwritten, within about three months. A sentence about the specific gift is all it takes to make the note feel personal.
Start the name-change paperwork (if changing)
Social Security first, then license, then passport, then bank and everything else. Keep a certified marriage certificate copy for each stop.
Preserve or resell your attire
Cleaning services can preserve a gown or suit within a few weeks. Or resell — many couples love giving their dress a second wedding.
Review your photos and pick prints
Print at least one large one for the wall — the phone album isn't the same. A photobook lives forever.
