Bridal salons will generally buy select pieces of a collection, not the complete one. Find out if your local salon is having a trunk show for the designer of the dress you're interested in.
A trunk show is where the designer and/or a sales representative from the company brings the complete collection to a salon -- that’s every dress for the season and probably a few other best sellers.
Call your salon and ask when the trunk show for a particular designer will be held and make an appointment. Trunk shows book up fast so be sure to make an appointment as soon as you learn the dates.
If you missed the trunk show dates for the season visit the designer’s website and look for another trunk show near you and schedule an appointment for that one. You can either purchase the dress .at that salon or see if your local salon can order it for you and this way you won't have to travel far for alterations, which you may have two to four of.
And remember, a trunk show usually offers a discount on the purchase of a gown, it's usually 10% off.
