How to Store Seasonal Clothes (Without Ruining Them)

September 8, 2026 | Guides

September is when most people finally admit the linen isn't coming back out and start looking for somewhere to put it. It's worth doing properly, because the cost of doing it badly isn't inconvenience — it's opening a box next May to find yellowed underarms, a moth hole through the shoulder of a jumper you loved, and a faint smell you can't get out.

None of that is bad luck. All four of the common ways stored clothes are ruined — moths, mildew, staining and crushing — are prevented by things you do in the hour before the lid goes on.

Do the Sorting First

Never store something you already know you won't wear. Storage is not a decision; it's a delay, and it costs you space and effort twice — once packing it and once unpacking it — for a garment that was already finished.

So sort before you pack, into three piles: keep and store, repair then store, and out. Anything unworn across the whole season just gone belongs in the third pile unless there's a specific reason it wasn't worn. Our guide to decluttering your wardrobe has a fuller method if the decisions are hard, and running cost per wear over the borderline items is a surprisingly effective tiebreaker — a garment worn twice in a season isn't earning its shelf.

The repair pile matters too. A missing button or a small seam split is far easier to fix now than in eight months, when you'll have forgotten it and will discover the problem on the morning you wanted to wear the thing.

Wash Everything, Without Exception

This is the step people skip and the one that causes most of the damage.

Clothes that look clean carry traces of sweat, body oils, perfume, deodorant and lotion. Left in a sealed box for eight months, those traces oxidise into yellow-brown stains that are far harder to remove than the original mark would have been — which is exactly why care guides insist on laundering before packing away.

They're also the reason moths find your wardrobe worth eating. Clothes moth larvae feed on natural fibres, and they're drawn to fibres carrying food and body residues. A clean wool jumper is much less appetising than a worn one, so washing is simultaneously a stain measure and the most effective moth measure available.

Two rules follow. Everything gets cleaned, including things worn once. And everything must be completely dry before it goes in — packing a garment that is even slightly damp is how mould and mildew take hold in a sealed container.

One extra trick for cotton and linen: iron them before packing. The heat destroys any moth eggs already present, which is free insurance on top of a job you'd have to do anyway in spring.

Choose the Right Container

This is where most advice oversimplifies, because the best container genuinely depends on the fibre.

Plastic tubs with tight-fitting lids are the reliable default. Wipe them out, let them dry, and line them with a clean cotton sheet, muslin or acid-free tissue so garments aren't sitting directly against plastic. They keep out dust, insects and light, and they stack.

Vacuum bags save the most space and seal pests out completely, which makes them excellent for synthetics, cottons and bulky-but-robust items like fleece. But they are the wrong choice for wool, cashmere, silk and down. Those fibres work by trapping air — that loft is the insulation and, in cashmere's case, the softness — and months under compression crushes the structure, can weaken fibres, and may leave creases that don't fall out. Recovery can take about as long as the storage did. If you vacuum-pack a down coat in September, it may not be properly lofted again until well after you needed it.

Breathable containers — cotton garment bags, canvas bins, archival boxes — are the right answer for natural fibres, because they let moisture move rather than trapping it against the cloth.

Cardboard boxes are the one option to avoid. They attract insects and absorb damp; if there's no alternative, use new ones rather than the pile behind the shed.

And never store anything in the thin plastic bag it came back from the dry cleaner in. It traps residual solvent and moisture against the fabric, which is the opposite of what long storage needs.

Where to Put It

Cool, dark and dry, in that order of importance.

Lofts and garages are the most popular choices and the two worst: both swing between extremes of temperature and humidity across a year, and damp is what turns a stored box into a mildew experiment. Under a bed, on top of a wardrobe, or in a spare-room cupboard inside the heated part of the house is far better, even though it uses space you'd rather keep.

Keep boxes off concrete floors if you have no choice about the garage — a pallet or a couple of battens is enough to stop moisture wicking upwards.

Moth Prevention That Works

The order of effectiveness is not the order people usually try.

1. Clean clothes. Already covered, and by far the most effective single measure.
2. Sealed or well-closed containers. Moths cannot lay eggs in what they cannot reach.
3. Cedar. Cedar wood repels moths in ball, chip or block form, but two details matter: keep it from touching garments directly — slipping it into an old sock or stocking is the standard trick — and refresh it. Cedar loses its scent over a few years and needs replacing or a light sanding to bring the oils back.
4. Dried herbs. Lavender, rosemary, mint, thyme and cloves all act as deterrents, used singly or blended in sachets tucked between layers. Pleasanter than mothballs and more or less as effective in a sealed box.
5. Heat. Ironing, as above, for anything that can take it.

What doesn't work is putting a deterrent in with clothes that were packed dirty. The residue is the attraction; a lavender bag will not out-argue it.

Moisture Control

Silica gel packets are cheap, and a couple in each container absorbs the excess moisture that causes mildew. Check them when you rotate the box and replace or dry them out if they feel damp — a saturated packet does nothing.

If you're storing in anything less than ideal conditions, this is the cheapest insurance available, and it's the difference between a musty smell and none.

Fold or Hang?

Fold anything knitted. Hanging a heavy jumper for eight months stretches the shoulders permanently, and no amount of steaming brings the shape back.

Hang structured garments — coats, suits, tailored jackets, dresses — on shaped hangers rather than wire ones, in a breathable garment bag rather than plastic. If you're short of hanging space, folding a coat with the sleeves tucked and tissue in the folds is a reasonable compromise; crushing it into the bottom of a box is not.

Photograph It Before It Disappears

The forgotten cost of seasonal storage isn't damage. It's buying things you already own.

Everything in that box is invisible for eight months, and by March most people genuinely cannot list what's in there. That's how you end up with a fourth striped linen shirt — not carelessness, just a wardrobe you can't see. The fix takes ten minutes: photograph the contents before the lid goes on, or add them to whatever wardrobe app you use, so that the stored half of your clothes still exists somewhere you'll look.

Our guide to photographing clothes for a wardrobe app covers getting usable shots quickly, and if you're using an app that generates outfits, having the stored items catalogued means they come back into rotation the moment the season turns rather than three weeks later when you finally open the box. Our autumn outfit ideas piece is a good example of what a fully visible wardrobe makes possible.

Bringing It Back Out

Unpack a week before you need the clothes, not the morning of. Compressed items need time to recover their shape, folds need to drop, and anything with a storage smell needs air.

Hang or lay things out somewhere ventilated for a day or two. Most storage odours disappear on their own; if they don't, that's a signal the container or the location was damp, and worth fixing before next season. Check for damage while you're at it — moth holes are much easier to repair when you find them in September than when you discover them in a hurry in December.

Then do the sort again in reverse: anything you unpack and immediately think "why did I keep this" goes out now, before it takes up another year of space. Our guide to organising your wardrobe covers getting the returning season back into a layout you can actually use.

Frequently Asked Questions

Are vacuum bags bad for clothes? For synthetics, cotton and hardy items, they're fine and space-efficient. For wool, cashmere, silk and down, prolonged compression crushes the loft that gives those fibres their warmth and softness, and recovery can take as long as the storage did. Use breathable containers for those.

Do I really have to wash everything first? Yes. Invisible body oils and product residues oxidise into stains over months, and they're what makes stored clothes attractive to moths in the first place. It's the single highest-value step in this whole process.

Do mothballs work better than cedar? Mothballs are effective but the smell permeates fabric and lingers, and many people find it unacceptable in clothes they then have to wear. Clean garments in sealed containers, with cedar or herb sachets, achieve most of the benefit without the smell.

Where should I not store clothes? Lofts, garages and basements, if you have any alternative — temperature swings and damp are the problem, not the space. Failing that, keep boxes off the floor and use silica gel.

How often should I check stored clothes? Once mid-season is plenty. Open a box, check the silica gel, look for any sign of insect activity, and close it again.

The Short Version

Sort first and don't store what you won't wear. Wash and fully dry everything. Use lined plastic tubs as your default, breathable containers for wool, cashmere, silk and down, and vacuum bags only for robust synthetics. Keep it cool, dark and dry — inside the house, not the loft. Cedar or herbs, kept off the fabric, plus silica gel. Fold knits, hang tailoring.

And photograph the lot before you seal it, so that next spring you know what you already own.
