Direct answer
The most important step in seasonal storage is washing everything before it goes away. Storing clothes with body oils, sweat, or food residue attracts moths and sets stains permanently. Beyond that, the right containers, a cool dry location, and a few fabric-specific considerations will keep clothes in good condition until you need them again.
Wash or dry clean everything before storing
Clothes that look clean often aren’t. Body oils and light sweat residue are invisible but attract moths and other pests, and they set into fabric over months of storage in ways that are very difficult to remove later.
Wash every item before it goes into storage, including things you only wore once or twice. Wool and cashmere in particular should be cleaned before storing since moth larvae are drawn to the protein in animal fibers and target soiled areas first. Dry clean anything that needs it rather than skipping the step.
Sort before you pack anything away
Before anything goes into a storage container, go through what you actually wore during the season. Anything that didn’t get worn, no longer fits, or needs repair is better dealt with now than rediscovered next season.
Set aside items that need mending before storing. A loose button or a small tear won’t fix itself in a box, and pulling out a damaged item next season means it still can’t be worn.
Choose the right containers for each fabric type
Not everything belongs in an airtight plastic bin. The right container depends on what you’re storing.
Breathable cotton or canvas storage bags are the best option for wool, cashmere, and other natural fibers. These fabrics need some airflow to stay in good condition. Sealed plastic traps any remaining moisture and can cause mildew or a musty smell over time.
Plastic bins with lids work well for cotton, synthetic fabrics, and most casual clothing. They keep out dust, pests, and moisture effectively. Clear bins make it easier to identify contents without opening everything.
Garment bags are the right choice for structured pieces like suits, blazers, and formal wear. Use breathable fabric garment bags rather than the plastic dry cleaning bags, which trap moisture and can cause yellowing on some fabrics over time.
Add moth protection for natural fibers
Wool, cashmere, silk, and other natural fibers are vulnerable to moth damage during storage. Cedar blocks or cedar hangers repel moths naturally and are safe to use directly with clothing. Replace or sand them lightly each season to refresh the scent, which fades as the cedar dries out.
Lavender sachets work similarly and are a good option for drawers and bins. Avoid mothballs if possible, they’re effective but leave a strong chemical smell that is very difficult to remove from fabric.
For valuable wool or cashmere pieces, storing them in a sealed container with cedar inside is the most reliable approach.
Store in a cool, dry, dark location
Heat and humidity are the main environmental factors that damage stored clothing. A cool, dry space away from direct light keeps fabric in the best condition. Attics are often too hot in summer. Basements can be too damp. A bedroom closet shelf or under-bed storage in a climate-controlled space is usually the better option.
Avoid storing clothes near exterior walls in climates with significant temperature variation. Condensation can form on cold walls and introduce moisture into storage containers.
Fold, don’t hang, most stored items
Hanging clothes for months puts continuous stress on the fabric at the shoulder points and can distort the shape over time, particularly for knitwear, heavy wool pieces, and anything with stretch.
Fold and stack most items for long-term storage. Knits and sweaters should be folded and laid flat rather than stacked too high, since the weight of items above compresses and distorts them over time. Structured jackets and formal wear are the exception, as these store better hanging in a garment bag.
Label everything clearly
Clear bins and good labeling make retrieving seasonal clothing faster and less frustrating. A simple label noting the season and general contents is enough. If you use opaque bins, a more detailed list on the outside saves time when you’re looking for a specific item.
Labeling also helps when storage spans multiple locations or when items are stored in a space used by more than one person.
Refresh clothes when you bring them back out
Clothes that have been stored for several months often need a quick refresh before wearing. Air them out for a few hours before putting them away in your wardrobe. Steaming removes any storage creases and freshens fabric that has been packed away for a while.
Check wool and cashmere items for any moth damage before hanging them with the rest of your clothes. A small hole now is easier to deal with than discovering it has spread.
What doesn’t work
Storing unwashed clothes. This is the most common mistake and the hardest to undo. Stains set, odors intensify, and moths are drawn to the residue. Always wash first.
Plastic dry cleaning bags for long-term storage. They trap moisture and can cause yellowing on light fabrics over months. Transfer to breathable garment bags instead.
Vacuum storage bags for wool and down. Compressing these materials for extended periods damages the fibers and crushes the insulation in down items. They work for bulky cotton or synthetic items but should be avoided for anything that needs to maintain loft or structure.
Storing in direct sunlight. Even indirect light through a window fades fabric over time. A dark storage location preserves color in stored clothing.
Skipping cedar or moth protection for natural fibers. A single moth can cause significant damage to a wool or cashmere collection over a season. Prevention is far easier than dealing with the aftermath.
Seasonal storage is one of those tasks that takes maybe an hour to do properly and saves you a real headache six months later. Wash everything, pick the right containers, and tuck in some cedar for anything wool or cashmere. That’s mostly it. You’ll pull your clothes out next season ready to wear instead of spending a weekend dealing with stains that have been setting since March.
