Depends on the wedding and the bride's personal style. Church wedding, absolutely perfect. Registry wedding with bride with less conservative taste? Probably best to avoid.
I do think as more Americans post on MN the dislike of white dresses for weddings increases on these threads, it's much more of a faux pas there. 20 years agoin the UK unless you turned up in an actual wedding dress nobody would bat an eyelid at a white dress.
