Don’t put off hanging your suit on a device that will preserve its shape. A chair won’t do, nor a coat rack. Hang the jacket on a round-shouldered wooden hanger to hold its shape and allow it to air out. Use the Savile Row fold to hang your trousers. Keep your suits in a closet with small boards or balls of cedar wood to avoid moths. Store your out-of-season suits in airtight bags.
Steaming your suit or coat opens up the fibers of the fabric and removes smells. Steaming also takes out minor stains, marks, creases and folds. Dry irons are too hot and can burn the fabric of your suit or coat.
Dry cleaning is really hard on suits. Each time a suit is dry cleaned, its lifespan is shortened. Only take your suit to the cleaners if a noticeable smell remains or there’s a stain that can’t be cleaned with a bit of water or stain remover. Cleaning only the jacket or only the trousers might result in a difference in color or wear.
