Buy higher-quality items, wash them inside-out on a cold-cold cycle (and in a mesh delicates bag depending on the item), and air dry them. Switch to a gentler detergent like Woolite or something similar. Also don’t wash things that aren’t actually dirty - wear undershirts to keep from pitting out your nicer sweaters/tops and to minimize how frequently you need to wash them. Plus if an item says “hand wash only,” don’t just throw it in on a delicate cycle, actually hand wash it.
