How to use: Simply slip the blue bandeau on under your sheer top or low - cut shirt. It's strapless, so it stays in place on its own. You don't have to worry about any straps showing. Attention: Although it's stretchy, don't over - stretch it when putting it on or taking it off to avoid damage. Maintenance: Hand - wash the bandeau in cold water with mild detergent. Then, lay it flat to dry. This will keep its shape and color intact for a long time.
