To make a dead bride costume, find a white dress. If there isn't one in your wardrobe, look at a local thrift store for some cheap options that will only cost a few dollars. Then, get some scissors and make the dress frayed. Cut up the hem or sleeves to make it look worn and old. Mix some gray paint with water and mist it on the dress to create the "dead" or aged look. Make a bouquet out of dead flowers to carry around and pair the dress with gray or black shoes.
To complete this scary costume idea, put on white foundation to give your skin a very pale appearance and dark eye makeup. If going for a slightly gruesome look, mix some red food coloring with corn syrup and apply to yourself or the dress. This is a simple and easy way to dress up as a dead bride for Halloween!
