Coming prepared for a bridesmaid dress fitting is important to ensure the dress fits properly. Wearing the exact shoes you plan on wearing to the wedding is critical since even a slight change in heel height can result in a dress that is the wrong length. Wearing the same undergarments or shapewear to the fitting is also helpful, especially when you are having the side seams or bust altered.
If you plan on wearing your hair up for the ceremony, it is a good idea to do a similar style for your dress fitting. This allows you to see if straps or necklines require any alterations to achieve the look and fit you want.
