Wash black clothing only with other black or dark colors. It also helps to turn the clothing inside-out, so that any stray lint adheres to the inside of the garments. Use dryer sheets to cut down on static cling when drying black clothes. Also, treat black garments with anti-static spray each time you put them on. Purchase one of those gizmos that shave pills off fabric.
Pills are terrible lint-traps.
Invest in several lint brushes and keep them in strategic locations such as your bedroom, bathroom, car and office desk drawer. Use them frequently. If you like pets, choose black ones. I am in my late 40s. I will be wearing a simple column gown with scoop neckline and three-quarter sleeves.
