So, we are kind of obsessed with Jessica Seinfeld. Her cookbooks make us less intimidated to prepare seemingly complicated meals. We follow her on Instagram and Twitter and find her to be smart and hilarious. (Coincidentally, she’s married to comedian Jerry Seinfeld.) We also love her sense of fashion. When we saw a picture she posted on Instagram in which she is holding her iPhone that was adorned with a case that we had to know more about. Although we are unsure of the brand of case Jessica has, we found the Valentino Rockstud Knuckle Duster Hardcard for iPhone 5/5s ($875). Radiant and edgy, this polished style features signature, pyramid studs and a on-trend, knuckle duster side. Whether or not this is the exact case that Jessica has we are not sure, but we had not seen a brass knuckle style case until we saw her picture. We love the style of this fashion-forward iPhone case.
