Ask the bride what she thinks. I think you should dress in the wedding colors, but not TOO similar to the bridesmaids, so that no one confuses you with a bridesmaid. Also, please dress like a mom... a dress with sleeves or at least straps, and doesn't show your cleavage when you bend over, or else your boobs will be all over their wedding photos (18 months old are short!).
There are lots of cute outfits that are covering.
Ok,just wear a formal dress. I got to know a online shop which called www.storeofdress.com they have many wedding dresses for shopping online,and I have ever got my dress from them,exactly nice and in low price.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
