I'd say a coach mini skinny, lv cles, balenciaga coin purse would look fab. or if you like a lot of color, vera bradley's coin purses are great (and cheap!). i use mine to hold my digi cam or ipod
I like Prada! They have a squarish coin purse which opens up into a box? Sorry, don't have a picture hehe..my mom took it, cause it was useful!
have fun picking!
