Recently it came to my attention that certain Karl Lagerfeld Paris shoes have the same distinguishing feature as Roger Vivier shoes. The metal ornaments at the toe box most definitely bear resemblance to each other, as well as the Manolo Blahnik Hangisi style made popular by Carrie Bradshaw.
I am a fan of the flats as they can easily be incorporated into even a denim-based outfit. With a button down and a blazer? Um, yes.
