I love the Proenza Schouler Patent PS1 bag. This hot black patent PS1 comes in three sizes (a pochette, a medium, and a large) and available exclusively on www.proenzaschouler.com. According to style.com, “using a new system Proenza Schouler developed, layers of transparent lacquer are “painted” on the skin, rather than the traditional method of layering plastic on top of the surface of the leather. The result is softer, more subtle, and more liquid-looking than the competition.” This patent is one of my favourite bags this season, it would be perfect for work or school.
