The wedding dress trend currently is white or ivory, as this symbolizes purity.
This is a newer superstition because white was started to be worn as a wedding dress only during the Victorian age over a hundred years ago that.
These days, it is customary for the bride to decide what color and fabric the bridesmaids will wear, and the bridesmaid will then choose the most flattering style for herself.
Some brides choose the other way around, they choose what style the bridesmaids will wear, and the bridesmaids wear different colors of the same style dress.
This is a headache for the brides who want to make sure everything should be perfect on the day. Some who still want to follow this superstition fit the lining of the dress, and leave all trust to the dress maker.
