Summarize this article in one sentence.
Cheap, flimsy wire hangers might be enough for the rest of your wardrobe, but a wooden hanger is ideal for hanging your suit. This will ensure it retains its shape, whereas wire hangers tend to cause wrinkles and will even deform the jacket’s shoulders. Additionally, hangers made of cedar naturally repel one of your suit’s worst enemies: moths. Suits are usually sold in plastic garment bags, to ensure they don’t suffer any damage on their way to your closet. However, this is far from a long-term solution: suits shouldn’t be kept in an airtight environment. Plastic garment bags don’t allow the suit to breathe and can tear easily. This can lead to nasty odours and easy access for moths. You can find cloth garment bags rather easily; stores usually sell them if they sell suits. Important things to consider before buying are:  Compare the length of the bag to that of your suit. You don’t want the suit to get bunched up while it’s stored. You can and should be storing dress pants with their respective jackets. Extra features that aren’t needed but can be handy include cedar linings and extra zipper flaps to ward off insects. While great for chilly holiday party weather, wool suits aren’t particularly suited for summer events. Beyond being sloppy and possibly permanently dirtying your suit, lingering stains and odours make your suit particularly attractive to moths and other insects. Remember not to dry clean your suit more than a few times a year. More than this and you risk damaging it.
Use a wide-shouldered wooden hanger. Store your suit in a cloth garment bag. Dry clean your suit before storing it for the season.
