I am looking for any suggestions for shopping for bridesmaid dresses for my 4 bridesmaids - 1 of whom will be 8 months pregnant at the wedding. Since my wedding is a year and 3 months away - let me explain a little. My FBIL and his wife are planning on getting pregnant with their 2nd child in the spring ~ a plan they have had in place for quite a while as it is very important to them to have their 2nd baby before their first turns 2 (Their son will be 2 in Feb 2013). I respect their plans and what they are trying to do but want my FSIL to still be a bridesmaid in the wedding. I am trying to plan in advance as far as chosing a dress with either an empire waist or something that comes in maternity sizes but I am hoping for suggestions as to places to shop that others with similar situations have dealt with and had positive outcomes or just suggestions in general as to how I can make this work so FSIL ends up with the same dress as the other girls and making sure it fits the day of the wedding.
I apologize for this being so long - it is very important to me that she be a bridesmaid so any and all suggestions would be appreciated!
