Reduce the frequency of laundry day
Washing and drying your clothes often will damage the colour and fit. The best way to combat this is to keep your clothes clean so you don't need to wash them as often.
While this can seem like an easy solution, most women avoid wearing undershirts to protect from sweat stains and everyday wear. The right undershirt can help keep your clothes clean so you can confidently wear it several times before it becomes necessary to wash them. This is one of the best ways to extend the life of your clothes and avoid shrinking.
Read and Follow the Labels
All clothing pieces come with a list of do's/don'ts of laundry, most labels will specify the best way to wash your clothes to avoid damages. Whether this means dry cleaning, washing at home, specific water temperatures or laundry cycle, it's important to pay attention. If the label indicates it has been pre-washed it will not shrink as much over the course of its life.
Wash with Cold Water
While this does not guarantee that you will avoid shrinking your clothes, cold water is not as damaging on the fabrics as warm and hot water are. Hot water can cause your clothing to relax and release tension which will result in the fabric becoming misshapen. Most modern washing machines and detergents can remove dirt as easily in the cold water setting, but to ensure they are properly cleaned add a bit more detergent in your wash next time.
Air Dry Your Clothing
If you really want to do your best to prevent shrinkage, it is best to air dry your clothes. This is the safest method. If you have any loosely woven or knitted clothing it is best to roll it out in a towel and leave it on a flat surface to dry. Avoid hanging clothes on hangers to dry as the added weight of the water will result in stretching of the fabric, instead drape them over a rack or hanger.
If you prefer not to air dry your clothing but still want to ensure it does not shrink then select a lower heat setting on the machine and take the clothes out while still a bit damp. This will prevent the clothes from over drying which is harmful to the fabrics.
