Design some Fashion

Design a fashion-forward mobile phone case cover with a difference - on a cross body strap. Classic, elegant, minimalist design. To appeal to the fashion conscious woman who wants more out of her mobile phone accessories - to be hands free, to be more than just a phone holder (credit cards and cash (notes)), and to be stylish. Picture shows base design. The task is to replace the Chanel classic flap with a different design. Still needs to be a flap, to be no more than one third of the width of the phone. The flap will be magnetic so that it stays firmly closed. Looking for a different shape to the flap.
