How many bras you need and why rotation matters

Short answer: Three to five in rotation. A bra needs a day to get its elastic back, and if you wear the same one every day, it lasts less than half as long.

Elastic needs rest

Elastic is stretched through a day and contracts again when it rests. Without a rest day the stretch becomes permanent. See bamboo bra without underwire.

Three is the minimum

One on, one in the change and one in the wash. Fewer than that means the same one is worn two days running.

Different models for different days

A soft one for home, a lightly padded one for close fitting clothing and a sports bra cover most days. See bamboo sports bra.

Wash less often than you think

A bra does not need washing after every wear unless you have sweated. Every third or fourth time is enough. See washing and care.

Replace as you go

Change one at a time rather than all at once. See bamboo underwear for women.
