Most seamstresses recommend starting fittings 8-12 weeks before your big day, but it is best to touch base with them to ensure you are working within their preferences.  Here is a sample timeline:

• First fitting – about 8-12 weeks before your wedding day.  At this fitting, the initial pinning will take place and the bustle will be determined.  Remember, now is the time to speak up!  If you see something you want changed {placement of applique, removal of beading, adding a strap or bra cups, etc.} this first fitting is the time to do it!
• Second fitting – about one month before your wedding day.  This fitting is to check the initial pinning and fit and to make minor adjustments.  Keep in mind that this may be a final fitting for you if all feels and looks good with your dress.
• Third and fourth fittings – anywhere from 1 week to 3 weeks before your wedding day.  Many brides will have a third fitting but fourth fittings are pretty rare.  These fittings are to ensure the minor tweaks that have been made are done to your liking.
