I have no idea how to describe my love for Proenza Schouler's fabulous design, especially for the signature PS1 handbags. It has already become a must-have item for the celebrities, models and fashionistas. Now, here is a new-designed PS1 bag called Keep-all. Based on the signature shape, the top handle is transformed into a more "feminine" look. I really think Leighton Meester can be the best spokesperson for the PS1 bag, she is always spotted carrying PS1 bags in different colors, same for this new Keep-one bag. The Keep-all comes in two sizes, small ($1,150) and large ($1,350). Check them out here.
