To help your zippers, close the zippers before washing. Use a gentle cycle for zippered items, so the stretching is lessened. Then hang to dry, or use a drying rack, flattening the zipper. The more you put them through a wash or dry cycle, the more they will warp, and the fabric will stretch around the zipper. Dresses, pants, and sweaters all are prone to zipper issues from washing.
When washing bras with hooks, close the hooks so they don’t grab other pieces of fabric and get pulled out of whack. If the hooks do get bent, get some pliers, and then bend the hooks back to shape. You might want to wash them in a mesh bag, as well, so they stay away from other clothes. Then dry them by hanging or on a drying rack – the elastic can get fail in the dryer.
When washing Velcro, close the 2 pieces together, and use a mesh bag to keep them from detaching and re-attaching to other clothes.
Elastics in clothes – wash them in colder water and don’t put into the dryer (same for sport bras, swimsuits, stretchy athletic clothes, etc.). The elasticity goes downhill with heat. Make sure to use clothes with elastic bands – elastic dries out and fails if it sits unused in a closet or in drawers. Some elastic is difficult to repair as it is sewn into the clothes – elastic in drawstring form is much easier to replace. Make sure to use the correct temperature for clothes - most colors need cold or lukewarm water so they don't bleed the colors nor shrink. Whites can usually be washed in hot water to combat germs. Put potential shrinkage items and tee-shirts with iron on appliques in the cold water wash and don't put them in the dryer - dry flat. Not all "dry-clean only" clothes really require it - many can be washed carefully in cold water and laid flat to dry - be very careful when you test this, as certain types of fibers and blends shrink in water and heat. Try Googling first if you have try this.
Take clothes out of the dryer while still damp and let finish drying on hangers or a drying rack – there will be less wrinkles on them. Hang things on skirt hangers - you can clip bags upside down (like reusable grocery bags) or dry ball caps on the clips. This is a good way to keep pants and shorts hems flat.
Do these and it will extend the life of your clothes. PR
