There are few people we love more than Lena Dunham, especially when she's wearing a two-piece (or is it a onesie?) with Bill Murray's face all over it. The author is about to start promoting her new book Not That Kind of Girl and for that she shared a snap of her wearing aforementioned item as she said Murray will "keep and protect" her when she's working. Whatever helps, right?
Other Instagram highlights this week include Kim Kardashian West and her daughter North West rocking Givenchy for the, you guessed it, Givenchy show at Paris Fashion Week. It's also when we discovered that it is possible to be jealous of a one-year-old's wardrobe.
Elsewhere in Paris, Stella McCartney and Cara Delevingne showed up ready to showcase the designer's latest wares, although they looked like they were up to no good. But perhaps the most exciting arrival at Paris Fashion Week was Barbie Lagerfeld, who is dressed exactly like the designer.
