SweetTops are made from a blend of rayon, polyester, and spandex. Rayon gives the fabric a luxuriously soft hand feel, polyester adds strength to the garment, and spandex allows it to keep its shape. We recommend you hand wash all SweetTops in cold water and hang them to dry to keep them looking new! Make sure to wash SweetTops with similar fabrics, and remember that abrasive pieces worn or washed with any garment may encourage rubbing of the fabric.
