I purchased my dress from David's Bridal back in mid-March and they informed me it is set to arrive around August 15th (eek!). My wedding date is October 1, 2016. Since it's cutting it so close to give enough time for alterations to be done, should I call ahead now and try to get an appointment now to make sure a slot is available in August? I will be going through an independent seamstress, not DB, so I'm worried about the issue of manpower and if the seamstress is only able to take so many dresses at a time. I'm not clear on the etiquette around alterations. Help!
