What is do bras shrink in the dryer?

As an AI language model, I cannot give you an assurance that bras do shrink in the dryer. However, bras can be made from different materials that react differently to heat. Some bras can shrink in the dryer, while others may not. It usually depends on the type of fabric the bra is made of, as well as the washing and drying instructions provided by the manufacturer. To prevent shrinking, it is generally recommended to hand-wash your bras in cold water and hang them to dry.
