Every cycle through the laundry removes more black dye and roughs up the surface, creating a fuzzy fade effect. Consumer Reports says, when you absolutely must wash, turn black garments inside out to protect the surface, sort items by color and weight, and wash in cold water in the shortest cycle possible. Avoid detergent with bleach and measure carefully to avoid streaking. Hang inside to dry, laying sweaters flat on a lint-free towel. Dry cleaning your favorite black items will keep the just-bought look a lot longer than laundering.
