DURING THE 60'S AND 70'S, THESE HOSTESS GOWNS AND LOUNGEWEAR WERE WORN IN THE HOME WHEN ENTERTAINING. THIS PARTICULAR ONE IS POLYESTER AND CAN BE WASHED BY HAND AND HUNG TO DRY AND CAME OUT AS PERFECT AS THE DAY IT WAS MADE. IT'S SO NICE NOT TO HAVE TO SPEND A FURTUNE ON DRY CLEANING WHEN SOME THINGS COME OUT EVEN BETTER BY BLOCKING SWEATERS AND HANGING CERTAIN ONES TO DRY!!!!! I DO IT ALL THE TIME WITH GREAT SUCCESS!
