It is recommended that all new undergarments, regardless of brand, be laundered prior to wearing. Never put garments containing elastic in the dryer. Hang them to dry in a cool dry place in a manner which will not distort the shape of the garment. For the Custom Fitted Bras, it means that hanging the cups upside down will allow the water to drain naturally away from the patented support collar. Some prefer to drape the upside down bra over an inflatable wash and wear hanger.
Elastic garments loose their life and elasticity when dried in a dryer.
The high heat breaks down the fabric. Of course, when we remove the lint trap in the dryer, we see that all fabrics have lost lint into the dryer lint trap. Elastic, however, is particularly vulnerable to degeneration in the dryer heat. Rinse, then wash thoroughly using a mild lingerie soap, not detergent, in a washing machine. Rinse thoroughly, even if you have to use several rinses.
