We recommend beginning the alterations process about 2-3 months before your wedding date. But it is never too early to start your wedding dress alteration. The sooner you are able to schedule your fittings, the better. This gives you plenty of time for your first fitting to be completed so that the seamstress will have plenty of time to work on your dress before your second and third fittings. The second fitting will be a month or so before your wedding, and the third or final fitting will be the week before your wedding. If additional fittings are necessary for custom changes, those will be scheduled in between your other fittings.
