During the first meeting, you will be trying on your gown and the seamstress will be making notes on the gown, where to bring the dress in, hem it to, or how much to take out. Your seamstress will also make note of the best way to bustle your gown in the back. At your second appointment, you can expect to try on your altered gown. This will be a time for you to make sure it feels right. You want it to fit you like a glove, not too tight, just right. And you can make sure you like the look of all the alterations.
