How to Store Cashmere Jumpers for Years

A fine cashmere jumper earns its place in a wardrobe slowly. It becomes the layer you reach for on cold mornings, long flights and winter dinners, softening beautifully with wear. Knowing how to store cashmere jumpers properly is what allows that familiar softness to return each season, rather than being spoiled by moth holes, stretched shoulders or a lingering stale smell.

Cashmere is exceptionally warm for its weight, but its delicate fibres deserve a little more care than a cotton tee or sturdy linen shirt. The good news is that thoughtful storage is simple. It comes down to four things: clean fibres, complete dryness, gentle folding and protection from pests.

Prepare cashmere before putting it away

Never pack away a cashmere jumper after its final wear of the season without cleaning it first. Even when it appears spotless, invisible traces of skin oils, body lotion, perfume and food can remain in the fibres. These are precisely what clothes moths and carpet beetles are drawn to.

Wash according to the garment’s care label. Many quality cashmere pieces can be hand-washed in cool water with a small amount of wool wash, then rinsed gently at the same temperature. Do not rub, wring or twist the knit. Instead, press out water with care and roll the jumper inside a clean towel to absorb the excess.

Some cashmere garments specify dry-cleaning, particularly if they have a structured shape, embellishment or a blended fibre composition. In that case, follow the label. It is better to choose the right cleaning method than risk changing the handle or shape of a much-loved knit.

Dry the jumper flat on a clean towel or mesh drying rack, away from direct sun, heaters and hot air. A hanger can pull damp cashmere out of shape, especially through the shoulders and sleeves. Allow more time than you think it needs. Storage is only safe once the garment is completely dry through the cuffs, seams and underarms.

How to store cashmere jumpers without stretching them

Cashmere should be folded, never hung for long-term storage. Even a beautifully made wooden hanger can leave shoulder dents and gradually lengthen the body of a fine knit. Smooth the jumper flat, fold the sleeves inwards, then fold the body loosely into a compact rectangle. Avoid sharp creases or overstuffing a drawer.

A clean drawer is ideal if it closes well and is not exposed to dampness, dust or direct sunlight. If drawer space is limited, use a breathable cotton storage bag or a lidded fabric box. Natural cotton allows air to circulate while keeping the garment protected from household dust.

Plastic tubs can be useful in some homes, particularly where there is a known moth problem, but only when the cashmere is utterly dry. A sealed plastic container with even a trace of moisture can trap humidity and create an unpleasant, musty environment. If you use one, choose a clean, dry, airtight tub and avoid packing it too tightly.

Vacuum bags are best treated with caution. They save valuable space, but the compression can flatten cashmere’s natural loft and leave stubborn fold lines. For short periods in a very small wardrobe they may be practical, but a breathable storage option is kinder to premium knitwear over a full summer.

Choose a cool, dry and dark place

The best place for cashmere is a stable, dry cupboard or drawer in the main part of your home. Avoid the garage, shed, roof space or damp laundry, where temperatures and humidity can shift dramatically. These spaces can invite mould, insects and moisture damage.

Keep cashmere away from windows and strong light. Sunlight can fade dyed fibres over time, while heat can make a closed storage space feel dry and brittle. A cool linen cupboard or bedroom wardrobe shelf is usually a better choice than the highest shelf near a hot ceiling.

If your home tends to feel humid through summer, place a small moisture absorber nearby, rather than directly amongst the jumpers. Check it periodically and replace it as needed. The goal is a dry, calm environment, not an aggressively sealed one.

Protect cashmere from moths naturally

Moths do not eat cashmere because it is cashmere. They are attracted to keratin fibres, including wool, merino, alpaca and silk, particularly when those fibres carry food or skin residue. Cleaning before storage is therefore the strongest form of protection.

After that, physical barriers matter. A closed drawer, cotton zip bag or well-fitted storage box makes it harder for moths to reach your knitwear. Before packing, vacuum wardrobe corners, wipe shelves and check nearby wool rugs, blankets and coats for signs of activity. Small holes, silky webbing, shed larval cases or tiny pale larvae are all reasons to inspect more closely.

Cedar blocks and lavender sachets bring a lovely, quiet fragrance to a linen cupboard and may help discourage moths, but they are not a complete solution to an active infestation. Cedar loses its scent over time and should be lightly sanded or refreshed occasionally. Lavender should be replaced when its fragrance fades.

Avoid placing strongly scented sachets directly against pale cashmere, especially if they contain oils. A small sachet tucked into the drawer or storage box is enough. For a more reliable approach, combine clean garments, enclosed storage and regular checks every month or two.

Do not overfill the drawer

It is tempting to stack every winter layer into one deep drawer once warm weather arrives. But cashmere benefits from breathing room. Tight stacks create creases and make it difficult to spot a moth issue early. They also encourage you to rummage, which can catch delicate fibres on zips, rough drawer edges or jewellery.

Store jumpers in small piles, with heavier knits at the bottom and finer pieces on top. If you have several colours, place tissue paper between very dark and very light garments if they are likely to sit together for months. This is not essential for every knit, but it offers extra reassurance for richly dyed cashmere and cream or ivory pieces.

Pilling is another reason not to cram knitwear. It is a normal feature of soft natural fibres, especially where friction occurs under the arms and along the sides. Before storage, remove pills gently with a cashmere comb or fabric shaver designed for knitwear. Work slowly on a flat surface and never tug at a loose fibre.

Check stored knitwear through the season

Cashmere does not need constant handling, but a brief check during the warmer months is worthwhile. Open the drawer or bag, look for insect activity and make sure everything still feels dry. Refold only if needed. This small habit is particularly useful after a spell of humid weather or if you have brought vintage woollens, second-hand furniture or wool rugs into the home.

If you find a hole, isolate the affected piece and inspect the surrounding garments. Wash or dry-clean the jumper as appropriate, clean the storage area thoroughly and consider professional pest treatment if the problem is widespread. A tiny hole can often be repaired beautifully by a skilled mender, particularly in a simple stockinette knit. Repair is part of the long life of natural fibres, not a failure of them.

Bringing cashmere back into rotation

When the first cool change arrives, take your cashmere out a day before you plan to wear it. Give each jumper a gentle shake, lay it flat and let the fibres air in a shaded room. If it needs refreshing, steam lightly from a distance or wash it again according to the care instructions.

There is no need to wash cashmere after every wear. In fact, over-washing can shorten its life. Airing it between wears, treating marks promptly and rotating your knitwear will usually keep it fresh. With careful storage, a cashmere jumper can remain one of the most comforting pieces in your wardrobe for many winters to come.

A well-kept cashmere layer carries the ease of quiet luxury: soft against the skin, light in the hand and ready when the season turns.
