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.

Wedding month — October 2026

32 tasks
  • 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.

After the wedding — November 2026

9 tasks
  • 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.
