A high-quality dress suit is one of the most expensive and important garments in a man's wardrobe. You may expect your suit to last for many years, but if it's not properly cared for, it might get worn out much sooner than that. Your suit will stay in good condition for a long time if you clean, dry and store it correctly after wearing it.
Brush your suit off with a stiff-bristle brush after each wear. This helps remove built-up crumbs and other debris stuck on the garment. If you don't do this, food particles may give off a bad odor or even attract insects.
Dry clean your suit only when necessary to prevent damage and wear. If your suit gets stained in one area, spot-clean it with a few drops of liquid detergent and lukewarm water.
Hang up your suit and let it air dry if it gets wet. Putting it in a clothes dryer will wear it out quickly.
Iron the suit when it looks wrinkled, or have a professional cleaner do it for you. Use the low heat setting for delicate fabrics, such as silk, and the medium heat setting for most other garments.
Hang your suit on thick wood hangers in a cool, dark closet. Use wood hangers that measure at least 1 inch thick. Do not use wire hangers; the metal will crease the suit and may damage it.
Store your suit in a breathable garment bag if you don't plan to wear it for at least one month. Leave the bag's zipper open slightly to allow the suit to air out.
Check your suit regularly for moths and insect damage if you store it for a long period of time. Moths lay eggs on and around clothing, and they will eat holes in many types of fabric. To keep moths away, put cedar blocks or bags of dried lavender buds in the closet with your suit. Commercial moth balls do work, but they often leave an unpleasant smell on clothing.
Give your suit at least one day to rest between wearings. This helps prevent the suit from wearing out.
Make repairs and alterations to your suit before lasting damage occurs. For example, if you see a button hanging by a thread, cut it off and sew it back on properly, or have a tailor do it for you. If you leave the button alone, it will likely fall off and get lost.
