Hangers deform more clothes than washing does, and nobody suspects them because the damage arrives slowly. A shoulder that has grown two small points, a neckline that has gone slack, a jumper that hangs longer on one side. None of that came from a machine.
Why hangers do damage at all
A hanger holds a garment’s entire weight at two narrow points on the shoulders, continuously, for months at a time.
Fabric under constant load stretches. Knitted fabric stretches a great deal, because a knit is a structure of interlocking loops that can be pulled longer, and it does not return once the fibres have taken a set.
Woven fabric resists better, but the shoulder seam is still bearing weight against a hard edge, and over a season that edge presses a shape into the cloth.
The thinner the hanger, the more concentrated the load. A wire hanger concentrates the whole weight of a coat onto about two square centimetres of shoulder, which is why wire hangers produce the little pointed bumps people call hanger bumps.
What should never be hung
The rule is simple. Anything knitted goes in a drawer.
Jumpers, cardigans, and knitted tops all stretch at the shoulders and grow longer down the body under their own weight. Fold them.
Anything heavily beaded or sequinned, where the weight of the decoration pulls the base fabric out of shape permanently.
Anything wet, without exception. Wet fibre is weaker and more extensible than dry, so hanging a wet garment does in one drying cycle what months of dry hanging would do.
Bias-cut garments, which are cut diagonally across the weave and will grow noticeably longer if hung.
T-shirts, which are knits, and which most people hang out of habit.
What should be hung
Structured and woven garments hold their shape better hanging than folded, because a fold line in a woven garment sets into a crease.
Shirts and blouses, on a hanger wide enough to fill the shoulder.
Trousers, from the hem on a clamp hanger rather than folded over a bar, which puts a permanent crease across the knee.
Jackets and coats, on a proper shaped hanger.
Dresses, provided they are woven rather than knitted, and provided the fabric is not heavy enough to pull at a narrow strap.
Choosing hangers that do not cause harm
Width matters more than material. A hanger should reach to the end of the shoulder seam and no further. Too narrow leaves the garment unsupported and creates bumps. Too wide stretches the shoulder outward and distorts the seam.
Shape matters second. A hanger with a gentle curve follows the line of a shoulder and spreads the load. A flat straight hanger concentrates it at the ends.
Thickness matters third. A thicker arm spreads weight over more fabric, which is the entire argument for wooden and padded hangers.
Velvet-covered hangers are genuinely useful for anything that slips, since a garment that slides off and lands on the floor takes more damage than one that stays put.
Throw the wire hangers away, or use them only for shirts going straight back out of the wardrobe.
The mistakes people repeat
Hanging a garment by its straps rather than supporting the body. A camisole on a hanger by two thin straps concentrates the whole weight on two small points, which is how straps stretch.
Overcrowding the rail, which crushes shoulders sideways and creases everything.
Hanging a jacket by one shoulder while in a hurry, which is where a lopsided hang starts.
Leaving dry cleaning in its plastic sleeve. The plastic traps residual solvent and moisture and it yellows fabric over months.
Leaving garments on the thin wire hangers that come back from a cleaner, which are meant for transport rather than storage.
Fixing a garment that has already stretched
Hanger bumps and stretched shoulders are often reversible, which people do not expect.
Wash the garment according to its label, then reshape it while damp and dry it flat. Fibres that have taken a set will relax in water and re-set in whatever shape they dry in.
For wool and cashmere specifically, this works well. Pat the shoulders back into line while damp, square the body, and let it dry flat.
For a stretched neckline on a knit, dampen the neckband only, gather it back to size, and let it dry flat.
Steam alone helps with mild bumps on a woven garment. Hold steam near the shoulder without touching, then smooth the area by hand and let it cool flat.
Folding well
Fold knitwear along the same lines each time, and refold stored items once or twice a year so a permanent fold line does not form.
Fold arms back rather than across the front, which avoids a crease down the middle of the chest.
Stack heavier items at the bottom, and do not stack so high that the items underneath are compressed flat.
The Denver part
Two local conditions bear on this.
The very dry air here is the first, and it changes how fibres behave in storage. Low humidity makes natural fibres less pliable, and a garment hanging under load in dry air takes a set more readily than the same garment in a humid climate. That is a real argument for folding knitwear here rather than treating hanging as a matter of preference.
Dry air also works in your favour on the repair side. Reshaping a stretched garment and drying it flat is fast in this climate, which makes the fix practical rather than a two-day project.
The seasonal wardrobe swap is the second factor. Colorado has a genuine four-season wardrobe, which means a large share of clothing spends six months in storage. Six months hanging under load is where most permanent shoulder damage happens, and the answer is to fold anything knitted before it goes away rather than leaving it on a rail through the off season.
Store off-season clothing somewhere with air movement rather than sealed in plastic, and away from a garage that swings from freezing to very hot.
Before anything goes into storage
Whatever you fold or hang for a season should go away clean. Body oil and salt left in fibre oxidise into yellow marks over months and they attract moths to anything made of wool.
The machines at our self-service laundry on East Hampden move enough water per cycle to rinse body oil out properly, which is what a garment needs before six months in a closet.
Our machines and the store are cleaned daily.

The short version
Hangers hold a garment’s whole weight at two narrow points for months, and knitted fabric stretches under constant load and does not return. Fold anything knitted, anything beaded, anything bias-cut, and anything wet. Hang woven and structured garments on hangers wide enough to reach the shoulder seam and no further, with a curve and some thickness to spread the load. Throw out the wire ones. Hang trousers from the hem rather than folded over a bar. And a garment already deformed can usually be recovered by washing it, reshaping it damp, and drying it flat.
