I have already chosen and ordered bridesmaids dresses for all of my bridesmaids, and they have already come in. However, I just received a call today from one of my bridesmaids and she is pregnant! I am SO HAPPY for her, however, we have a dress that she will not be able to wear as she will be 7 months pregnant at the wedding. The bridesmaids dress is from Davids Bridal....I'm not sure if they'll exchange it or not. Any ideas?
