Start shopping 10 months before your big day, if possible, because it takes a dress 16 to 20 weeks from the time you order it to arrive in the salon. Then, for standard alterations, expect two to three fittings over a period of two to four weeks, with the last fitting no later than two weeks before your wedding.
