How many bras you need
Short answer: Three to five is enough for most people. That allows rotation, which is what makes them last.
Why rotation matters most
A bra needs to rest between wears so the elastic can contract again. Wearing the same one every day, it is spent in under a year. With three in rotation each one lasts markedly longer.
What the three to five should cover
One in a skin tone for light clothing, one in black for dark, one for training and possibly one for special occasions. See bamboo bras without underwire and bamboo sports bra.
When a bra is finished
When you use the tightest hook all the time, the elastic is spent. It no longer supports, however good it looks. See bamboo underwear for women.
Frequently asked questions
How long does a bra last
With rotation and hand washing or a mesh bag, typically one to two years.
Does a bra have to be washed after every wear
No. Every third or fourth time is enough, unless you have sweated a lot.
Can a bra go in the tumble dryer
No. Heat destroys the elastic faster than anything else.
