Oh no CBG! What a dilemma. I totally understand that you don't want to talk to the bride now 3 weeks out from her wedding and ask her to make any changes, no need to stress her out. I like Limeslice and Appletree's advice about getting the dress altered.....I fell pregnant AFTER the bridesmaid dresses were bought (so I did it knowingly) and was almost 30 weeks pregnant at the wedding. I just got a panel laceup insert put in at the back and from front on, it looked exactly the same as the other girls. From behind, I actually thought mine looked nicer - LOL. Just a warning though, the adjustments cost me $150 - ouchies. But much better than starving yourself hun.
