Where To Begin
Start by browsing through bridal magazines, web sites and shows to see a variety of dress designs and styles. Then try on as many different types and styles of dresses as you can before you contact a professional seamstress. That way, if you plan to have your dress made, you will know what length of sleeves, skirt and train you prefer as well as which neck and waist designs work best for your body type. 

Design
If you haven’t found the dress of your dreams or if the dress you have in mind doesn’t exist, take your ideas, pictures, and dreams to a dress designer. Designers offer a variety of options, taking a sleeve from one dress and a bodice from another to design a gown especially for you. Many expensive original designer dresses with designer prices can be copied, allowing you to stay within your budget.

Hemming
Consult with a dressmaker on hemming your dress. Many dresses can be lifted at the waistline to avoid taking lace off the entire hemline, and without distorting the lines and design of the dress. Also ask about ways to bustle up the train so it is comfortable and convenient for you to get around in at the reception.

NOTE
Make sure you are wearing the shoes you will wear to your wedding when making any decisions about hemming. A slight difference in heel height can change the measurements.
Reserving Alterations Services
As soon as you have selected your gown, be sure to make an appointment to reserve services for alterations. Many bridal-alterations specialists are booked months in advance. Your bridal shop can recommend a reliable seamstress or may have someone they work with. Brides should be prepared to pay for alterations and include this in their budget. They are seldom included in the price of the gown.
