How to Store Clothes So They Last
How you store clothes between wears determines whether they come out next season looking the same, or stretched, yellowed, and musty. The right approach depends on the fabric: heavy knits need support they can't get from a hanger, while structured or floaty pieces need to hang so they don't crease. Get the folding-versus-hanging call right, plus a few habits around cleanliness and moisture, and most of what damages stored clothing is preventable.
Key takeaways
- Fold heavy knits like sweaters and cashmere; hang floaty fabrics like silk and linen.
- Wash everything before storing it — invisible stains yellow over time and attract insects.
- Use breathable canvas or cotton storage, not sealed plastic bags or bins.
- Make sure clothes are completely dry before storing to prevent mildew.
Fold heavy knits, hang the rest
Fold sweaters, cashmere, and other heavy knits. A hanger concentrates a garment's weight on two small points at the shoulders, and over weeks or months that's enough to stretch the fabric and distort the fit — the heavier the knit, the worse the effect. Textile conservators put it simply: flat, folded storage spreads a garment's weight evenly across the fabric, which is why it's the standard recommendation for fragile or valuable pieces.
Hang floaty and wrinkle-prone fabrics. Silk, chiffon, linen, and structured blouses do better on a hanger, where gravity keeps them smooth instead of creasing in a drawer. If you're hanging something with real weight to it, a padded or wide hanger distributes the load across more of the shoulder seam than a thin wire one, which helps limit the telltale "hanger bumps."
Never store anything that isn't clean
It's tempting to fold away a barely-worn shirt without washing it first, but stains you can't see are still there, and they get worse in storage, not better. Invisible soiling — sweat, food residue, body oils — tends to yellow or darken the longer it sits, turning a faint mark into a permanent one.
Those same soils are also what draws fabric-eating insects to stored clothing in the first place, which we cover in more detail in our guide to preventing moths. Clean everything before it goes into storage, and resist the urge to iron first — heat can set a stain permanently before you've had a chance to treat it.
Skip the plastic — clothes need to breathe
Sealed plastic bags and bins feel protective, but they trap whatever moisture is in the fabric or the surrounding air, creating exactly the damp, unventilated conditions that encourage mildew. Breathable containers — canvas garment bags, cotton bins, or acid-free boxes for anything delicate — let air circulate while still keeping dust and light off your clothes.
If you're storing something valuable long-term, the ideal environment is cool, dark, dry, and ventilated. Museums that store historic textiles aim for around 45% relative humidity and roughly 70°F, both held steady. You don't need to replicate a museum vault at home, but it's a useful reminder that stable, moderate conditions beat anything sealed or extreme.
Store bone dry
Never put away anything that's even slightly damp. Clothes need to be fully dry — line-dried or run through a vented dryer to completion — before they go into a drawer, bin, or garment bag. Trapped moisture in an enclosed space is the single biggest driver of mold and mildew in stored textiles, and once mildew sets in, the smell and staining can be difficult to fully reverse.
