When clothes get shorter but not narrower

Short answer: Knit shrinks most in length because the loops contract vertically. The width often holds. That is why t-shirts get short, not narrow.

The loops contract

The structure of a knit gives most movement in height. See bamboo t-shirts for women.

Heat triggers it

Hot water and the tumble dryer are the two triggers. Cold washing removes the problem. See bamboo clothing for women.

Most of it happens in the first wash

The fibres settle in the first wash. After that the change is small. See bamboo underwear for women.

Stretch while damp

A damp garment can be gently stretched back in length. See bamboo tops for women.
