How to Dye a Wedding Dress
Mix Your Dye
Put on your rubber gloves and mix up your dye according to the instructions on the label, using the dry weight of the garment to determine proportions. (For all-purpose dyes, Rit recommends one liquid bottle or two powder packages per two-ish pounds of fabric.)
If you want a wash of color, stick to the suggested ratio, but if you’re looking for an ultra saturated shade like a deep magenta or an emerald green, for example, you can double it.
For liquid dyes, shake well and add to your dye bath along with a teaspoon of soap. If using a powder, dissolve in around two cups of very hot water and do the same. For enhanced color, you can also add a cup of salt for fabrics featuring cotton, rayon, ramie, or linen, or a little over ¾ cup of white vinegar for fabrics containing nylon, silk, or wool.
