We’ve been obsessed with transparent accessories ever since Karl Lagerfeld sent see-through hard plastic cases as purses down Chanel’s runway last fall.   Our obsession reached new heights when Prada also showcased transparent plexiglass and plastic sandals and handbags for Spring 2010.  But since we’re not too keen on the idea of showing off the contents of our purse to just any old stranger, we’re turning to these bangles from H&M ($9.95) as a way to bring a little bit of the transparent accessory trend into our wardrobe.
