Laundering and Care of a Bra

Tips for keeping that new bra looking nice and fitting right!

Gentle detergents: Remember harsh detergents won't just damage your bras, they can also irritate your skin.

Cold water wash: Always wash your bras in cool water. Hot water will often shrink the material, causing the underwire to pop out.

Hand wash and hang: Fill the sink with cool water and mild detergent and agitate for a few minutes. Rinse the garment in cold water, being careful not to wring or twist it. Hang it to dry.
If you must machine wash. use a product and wash cycle designed for delicate fabrics.
Attach hooks and eyes to prevent tangling and snagging. For even better protection, place your garments in a zippered lingerie bag and wash them in the delicate cycle.

Alternate bras: Try not to wear the same bra two days in a row. The "rest" will allow it to retain its elasticity and regain its shape.

Fold to store: Underwire bras can be safely folded in the middle to store. Molded bras can be folded with one cup tucked inside the other.
