White is traditionally a symbol of purity and as it was, traditionally, every mans wish to marry a pure woman to be married in white was a sign that you were indeed pure and a "good catch".
However in todays social climate that is no longer the case. We are less fixated by what we should do or should be and more inclined towards what we want. In other words we are less bound by tradition.
The generation before have left us with a legacy of not staying in a relationship that isnt working. Divorce rates are high and so we have moved to a "try before you buy" society of living together to see if we get on. The traditional meaning of a white wedding no longer applies. My daughter was horrified at age 12 that her father and I had not lived together first. Her logical reasoning of "how would we know that we would get on" left her father speechless and us both feeling faintly stupid that we hadnt!!
In generations gone by not marrying in white meant shame on the family, she was in the family way or could be! Now marrying in white is a conscious choice just as marrying in cream or even red is a concious choice.
So should you wear white? Only if you want to!!
I did try on a white wedding dress however I happened to bear a strong resemblance to a certain friendly ghost!! Sometimes you dont know what will suit till you actually see it on!
