Hello! I have and LOVE my large smoke ps1. Wear it pretty much everywhere, but anytime I see a girl with a medium, I have a little bag envy, lol!!! Also, I would love to have a smaller size bag so that I stop carrying everything I own just because I can. KWIM? So, my question is..which one do you find you wear more often, what are the pros and cons. and do i really need both?? Thanks enablers!
