Hi ,have you bought the Maggie Sottero Vanessa's detachable halter strap? if not,i have a suggestion,please go to BUYER100 website,http://www.buyer100.com/product.php?productid=28254&cat=0&page=1 they can sell the Barbie Dress,crystal beaded sash separately,so i think the beaded detachable halter strap is also available. i only ordered the crystal beaded satin ribbon sash of Watters & Watters ' Roma from them before,the price is so great,and the quality is absolutely GORGEOUS! More than I expected!!!! Good luck to you!
