Care

When to retire a bra

Elastic loses recovery whether a garment is worn or not. At some point a bra stops being a bra and becomes a shape that used to be one.

There is no fixed lifespan, because it depends entirely on how often a garment is worn and how it is washed. A bra worn twice a week, hand washed and dried flat can stay useful for years. The same bra worn daily and tumble dried can be finished in months. Rather than counting time, run the tests.

The four tests

The loosest hook test. Fasten on the loosest hook and put it on. If the band is only firm enough on the tightest hook, and still rides up, the band elastic is finished. This is the definitive test and it is the one that matters.
The stretch and release test. Hold a section of the band flat between both hands, stretch it and let go. Live elastic snaps back immediately and fully. Tired elastic returns slowly or stops short.
The lie flat test. Put the bra down on a flat surface. The band and the elastic edges should lie flat. A rippled, wavy edge is permanent deformation and cannot be recovered.
The strap test. If both straps are on their tightest setting and still slipping, the strap elastic has gone. Straps take a constant load and usually fail before the band.

A bra whose band no longer grips is not a bra with a problem. It is a garment that has finished its working life.

Faults that end it immediately

A wire that has come through the channel. It will not stay put once repaired and it will damage everything it is washed with.
A wire that has bent out of shape and no longer follows the chest. Wires are heat treated and cannot be reshaped reliably.
A moulded cup with a permanent crease across it. The foam is heat set and the crease is structural.
A torn cup fabric under load, as opposed to a snagged thread on the surface.
Band elastic that has separated from its casing along a length.

Faults worth repairing

A missing or broken hook: The hook and eye tape can be unpicked and replaced with a matching tape. This is straightforward hand sewing and restores the garment completely.
A strap that has come away: Re stitching a strap at the attachment point is quick and durable, provided the fabric it attaches to has not torn.
A wire poking out of an intact channel: If the channel fabric is sound, the wire can be pushed back and the opening closed with a few tight stitches. If the fabric has worn thin, this buys weeks rather than months.
A snagged thread in lace: Work it back along its own path with a blunt needle. Do not cut it.
A slipping strap adjuster: Sometimes the slider has worn. A replacement slider of the same width can be fitted by hand and restores adjustment.

Extending working life

Everything in this section is about slowing the loss of elastic recovery. Rotate, so no garment is worn on consecutive days. Wash cool and gently. Dry flat and away from heat. Store without compression. Start every band on the loosest hook so there are two more settings available as the elastic relaxes. None of that is dramatic and together it makes a substantial difference. The mechanism is set out on elastane and stretch.

What to do with the finished ones

A bra that fails the band test is not usable as a bra and keeping it in the drawer means it gets worn on a bad morning, which is how a whole drawer ends up feeling unreliable. Take it out. Textile recycling schemes accept bras in most places, and some collect them specifically for redistribution; a bra with a broken wire is still recyclable as textile even where it is not reusable.

Before replacing anything, re measure. A bra that stopped fitting may have worn out or the body may have changed, and the two require different responses. How to measure takes five minutes and settles it, and fit through change covers the causes.
