does anyone own a pair? i went to the eyeglass boutique near me and saw these gorgeous pair of robert marc sunglasses. they're white and have swarovski crystals on the side...just wondering if anyone has a pair so they can give me advice on the quality of it. they're a little pricey so i'm not sure if i want to spend the $$ for them. i'm half tempted to return my chanel sunnies that i bought the other day and buy these instead, just because i haven't seen that many of them around.
