When should alterations begin? This calculator works backward from your wedding date to a recommended start day.
Recommended Start Day = Wedding Day - ((Alterations Lead Time + Buffer) x 7 days)
Example
Wedding on day 250 of the year, 8-week lead time, 2-week buffer:
Total Lead Time = 10.0 weeks (70 days) → Start alterations by day 180
Why Fittings Take Several Weeks
Bridal alterations commonly require 2-3 fittings spread across 6-10 weeks total, especially for dresses needing significant structural changes like resizing, hemming, or bustle installation - this isn't a same-day or one-visit process.
Why the Buffer Weeks Matter
Starting this process too close to the wedding date is a common source of last-minute stress, so building in extra buffer weeks beyond the base alterations timeline protects against tailor scheduling delays, shipping delays for the dress itself, or needing an unexpected additional fitting.
