The Dress Timeline Calculator

Sizes & dates only — we never ask your weight

Uses a plateau-aware curve — loss slows over time, so a straight-line guess runs late by month 4. Ours doesn't.

Your timeline — likely size 12 at the altar

  1. Jul 23 Shop — but buy the size 14 Order now in your projected mid-point size. Corset-back styles buy you two sizes of grace either way.
  2. Sep 5 First fitting Six weeks out. The seamstress pins the take-in plan; you should be a 14-ish and slowing down.
  3. Oct 3 Final fitting — then stop changing things Two weeks out. Final take-in to the true size 12. After this date the dress is frozen — no exceptions.
  4. Oct 17 The wedding. It fits.

How the math works

A plateau-aware decay curve fitted to your recent pace. Loss slows over time, so a straight-line guess runs late by month 4 — the curve budgets for the slowdown, then adds two sizes of corset-back grace on either side.
