There number of "on the street" style bloggers in the world has become so exorbitant that we often have to ask ourselves, How do we sift through the crap? Really, what a good "on the street" blog comes down to is an arresting aesthetic and a cheeky concept. Style blogger Ari Cohen has mastered this recipe at Advanced Style, an expansive tribute to chic senior citizens around the globe. Enlisting friends, photographers, actors, and makeup artists (we think he commissioned an international army to scour the streets), Cohen has compiled an array of wacky grandpas and classic uptown debutantes to create an interesting narrative in blog form.
